Tile Facts

  • Tiles per art file: 256
  • v1.3D max tiles: 4096 (
  • v1.4/1.5 max tiles: 6144
  • EDuke32 max tiles: [insert info]
  • Max tile dimensions: 1024x512

Editart is a program that allows you to modify the art files in games which use Ken Silverman’s Build Engine, such as Duke Nukem 3D, Shadow Warrior, Blood, and others.  This guide is written for use with Duke Nukem 3D (hereafter referred to as “Duke3D”), although most of the instructions will apply to other Build Engine games as well.

While Editart has some basic drawing capabilities, it is not a fully featured paint program.  Its primary purpose is for storing images, not creating them.  For that reason, drawing in Editart will not be covered extensively in this guide, save for the explanation of drawing commands in the Keylist section and a few other useful commands.

Each art file in Duke3D contains 256 art tiles.  There are thousands of art tiles available.  If you have Duke3D v1.3d, you will have 4096 tiles (0-4095) available in 16 art files (  If you have v1.4 or v1.5, you will have 6144 tiles (0-6143) in 24 art files (  Source ports such as EDuke 2.1 and EDuke32 have raised the limits substantially as well.

The art files account for all of the graphics used in the game (textures, sprites, weapons graphics, help screens, fonts, etc.) with the exception of certain cutscenes, which are stored in anm files.

Tiles can have dimensions of up to 1024 pixels wide and 512 pixels high.  Keep in mind that rotating and wall-aligned sprites, as well as walls, will not shade normally if their height exceeds 256 pixels, and standard (non-parallaxed) floor and ceiling textures will have glitches if their width and/or height meets or exceeds 512 pixels.  (This problem is rectified in the Polymost renderer present in JFDuke3D, Duke3Dw, and EDuke32.)  All of your art (with a few exceptions such as title screens and cutscenes) will conform to a single 256-color palette.


Getting Editart Running

You should run editart in your Duke3D directory so that you have immediate access to your modified art files in Build and the game itself. The following files should be in the directory along with editart.exe:

  • palette.dat (required)
  • tables.dat (required)
  • all art files (; required)
  • names.h (optional)

You will likely find the dat files already inside your Duke3D folder. If not, they can be extracted from the duke3d.grp file. The art files will almost certainly need to be extracted from duke3d.grp as well. To extract the art or dat files (or both), make sure you have a program called kextract.exe in the Duke3D directory with your Editart files. If it isn’t there, copy it from the Duke3D CD-Rom. Assuming you understand DOS, go to the folder that contains Duke3D. Type

kextract duke3d.grp
where is the file or files you wish to extract. To extract all the art files, replace it with *.art. To extract all the dat files, use *.dat.


Once you have all of the necessary files in the directory, run the Editart program. You should see a black screen with red lettering that reads “Loading”

Note that it is in fact loading all art files that follow in sequential order. If you are lacking an art file, such as, and up may not display correctly.

Important: If you extract a file from duke3d.grp using kextract, the program will overwrite any file of the same name in the same directory without prompt or warning.

Important: If you have copied files directory off of the Duke3D CD-Rom, they will probably be marked as read-only. You can quickly fix this in DOS by going to your Duke3D folder and typing attrib –r at the DOS prompt. Alternately, you could select all of the files in the folder in Windows, right click on them, select Properties, then uncheck the read-only box and click “apply” and “ok.”


The Editart Interface

Upon opening Editart you should see the following:

The bottom left corner displays the tile number. If the tile has been assigned a name, that name will appear beneath the tile number. In the center are the tiles dimensions in pixels (64 wide/32 high in the above image) and its animation setting. The bottom right corner displays the palette (the 256 colors that most of the artwork conforms to). The center of the screen displays the tile itself. If you move the mouse or press the arrow keys, you’ll notice a tiny cursor moving around the tile. You can use this tile for drawing pixel-by-pixel or for selecting areas for copying and pasting. The rest of the commands are based on various keys on the keyboard. See the keylist section for a complete listing.


Navigating and Saving Tiles

You can save pre-existing tiles to an external pcx file using editart. First, find the tile you wish to save. You can change tiles in three different ways. First, you can press the pageup/pagedown keys to cycle through the tiles one at a time. Secondly, if you know the exact tile number of the file you wish to view, press the G key. This will bring up the goto prompt.

Type in the tile number and press Enter to immediately bring up that tile.

The third method allows you to enter a selection mode where you can see numerous tiles at once. Press the V key. Your screen will look similar to the following image:

A flashing box surrounds tile 0. You can move this box around using the arrow keys, or scroll up or down rapidly with the pageup/pagedown keys. Once you have selected your tile, press enter to return to the original view mode.

Now that you have selected a tile, you can save it to a 256-color pcx file, which can be read by most paint programs. The first tile that you save will be named Capt0000.pcx. Each subsequent tile will add 1 to the number at the end of the tilename. Capt0001.pcx and Capt0002.pcx would be the next files saved, for example. Press either the B or F12 key to save the tile.

Important: Editart will only allow you to have 256 compatible image files (bmp, pcx, or gif) in the directory. If the number meets or exceeds 256, it will not allow you to save any more tiles until you’ve cleared some of them out of the Duke3D folder. It will also refuse to display more than 256 tiles in the list of available images for importing.

Important: If you have trouble seeing tiles clearly in tile selection mode, you can use the / key on the numeric keypad to decrease the number of tiles displayed. To increase the amount, press the * key on the numeric keypad. There are three settings, the default setting being medium.


Creating Import-Ready Images

Dimensions. If you’ve read through this guide from the beginning, you already know that the maximum tile size is 1024x512 and that rotating sprites, wall-aligned sprites, and wall textures should not exceed 256 pixels in height due to a shading “bug” (or limitation, as it was limited intentionally by the programmer to keep the frame rate high). You should also have read that non-parallaxed floors and ceilings will be glitchy if their width and/or height meets or exceeds 512. If you’re an experienced level creator, you’ve probably also noticed that graphics whose heights are powers of 2 (1, 2, 4, 6, 16, 32, 64, 128, 256, 512, or 1024) tile properly on walls, floors, and ceilings, while those with other height measurements cause glitches when they repeat on a wall or are skewed when applied to floors and ceilings.

Generally, a safe practice is to make wall, floor, and ceiling textures have dimensions that are powers of 2. This allows these textues to be used safely on any surface or as any type of sprite. However, wall textures and floor-aligned sprites can break this rule. Wall textures will tile properly with any width, so long as their y dimension is a power of 2. Floor aligned textures will also display correctly at any width as long as their height is a power of 2. Rotating (default) and wall-aligned sprites can be any width and any height up to 256 (unless for some reason they will never be shaded, such as the explosion or fire actors; these could then safely reach the maximum height of 512).

Palette Conversion. So now that you have the dimension limits down, you’ll have to worry about the palette. While I provided a zip file with palettes and instructions for use, you may wish to know how to get the default palette yourself. Simply save a tile in Editart, then open the pcx file in your favorite paint program. Most paint programs have an option to save the palette of the current image. If you cannot find this function, check your paint program’s help file.

Many paint programs won’t allow you to use all of their features if your image is in 256 color mode. You may wish to increase the color depth to 24 bit and then load the Duke3D palette once you’ve finished editing. If your image contains colors that simply cannot be matched properly in the Duke3D palette, you may be able to use a simple program called Texture Colorizer (available in the RTCM download section) to adjust your colors.

Texture Colorizer Tutorial

Texture Colorizer was developed by Jaimi McEntire at Eldermage Software. It allows you to select any number of colors from a 256-color palette and change all or part of an image's colors to only those colors you've selected. According to the program's readme.txt file, TC uses the luminance values (brightness) of the pixels to determine which of the selected colors to match it to.

The program works with bitmap files only (bmp), so you will need to convert the image you wish to modify. The palette is read from a second bitmap. For your convenience, I've prepared one for you here, along with a sample image. The next section will guide you through "colorizing" the sample image.


  1. Open Texture Colorizer. You'll see two windows. The blank gray window is the image window where your the file you wish to colorize will be opened. The other is the main window, and it houses the controls and the palette.
  2. Begin by clicking file/open palette (or click the get palette button) in the main window, then choosing your palette image (Duke3d.bmp if you're using the one I supplied). Click OK.
  3. Now open the image you wish to colorize (sample.bmp if you're using the one I supplied) by clicking file/open bitmap (or click the load bitmap button).
  4. You can increase the size of the image window by selecting a size from the dropdown box in the main window (1x, 2x, 4x, or 8x).
  5. Now let's assume we want to make the image green. Select the two rows of green shades from the palette using the left mouse button. You can either hold down the button and select adjacent colors to the first one you picked, or you can hold shift and click on each color. Try both to be sure you have the hang of it.
  6. Now you'll see three different colorizing tools in the main window, the brush, the box, and the image filler. Select the brush. You can change the size of the brush tip by clicking on one of the brush size boxes below the tool buttons.
  7. Left click on the image and, holding the left mouse button down, drag the tool along the image. Note the way the color changes. Now click the undo button.
  8. Select the box botton. The box tool lets you colorize rectangular sections of the bitmap. Click and hold the left mouse button on the image and drag the tool around the picture. Once you've seen how this tool works, click undo.
  9. Now click on the image fill button. This will convert the entire image instantly to the new colors. You can adjust how light or dark the colors are replaced by adjusting the slider-bar.


Special Palette Colors and Transparency Issues: A common problem when converting images to the Duke3D palette, even if they appear to convert properly, is the existance of fullbright colors in the image. Fullbright colors are indexed as colors 240-254 in the palette, and are located in the last row of the palette when viewed in Editart and most paint programs. These colors do not get shaded in the game. An example of fullbrights can be seen in the eyes of the Pigcop. You can see during the game that his eyes never darken, no matter how dark the rest of the sprite appears. Fullbrights can be useful for making permanently lit objects, but they can also be bothersome when converting images to the Duke3D palette. The zip file of palettes I provided includes one that replaces the fullbrights with a single unique color similar in shade to the transparency color, making it easy to spot.

Transparency is determined by the last color (color 255) on the default palette. This purple color happens to share the same properties as one of the fullbright colors; that is, it contains the same amount of red, green, and blue values as color 245. If you don't use a modified palette when saving a file with transparency in your paint program, the program will likely map the transparent color to 245 instead of 255. Using the modified palette will cause the transparent color to be mapped to color 255.

If you've already imported your image and find that the transparent color is incorrectly mapped, you can quickly fix this problem. Hitting the backspace key to select the transparent color. Now move the cursor over the part of the image that's supposed to be transparent. Hit the C key to automatically change all instances of the highlighted color to the transparent color.

File Types. Non-interlaced .gif files are recommended for importing into Editart.

Editart can also import 8-bit .bmp and .pcx files if their dimensions are 300x200. It seems to have no trouble with .pcx files of any size that were previously saved by Editart.


  • For standard walls, floors, and ceilings, make sure their dimensions are multiples of 2.
  • Rotating/wall-aligned sprites and wall textures should not exceed 256 pixels high due to a shading bug (though this is fixed in the Polymost renderer).
  • For sprites that are floor-aligned only, dimensions can be any multiple of 2 up to the maximum tile size.
  • Maximum floor dimensions should not exceed 256x256 pixels (this doesn't apply if using the Polymost renderer).
  • Save files that you intend to import in 8-bit, non-interlaced gif format. Consult your paint program’s help file if you need to.
  • Load the Duke3D palette on your image prior to saving.
  • Use a modified palette to prevent your transparencies from being solid.


Importing Tiles

This section assumes you are aware of the following:

  • When importing images, it helps to have prepared them as described in the previous section.
  • Editart can convert images to the current palette, but usually does not do as good a job as a proper paint program.
  • You won't need to do any preparation to import images that have been saved from editart and haven't been modified.

Find the tile you wish to import your image to. Set the size of the tile to the dimensions of the image by pressing the S key. First type the width (x dimension) and press enter. Then do the same for height (y dimension).

Press U to begin importing. This will bring up a directory listing. Files that can be imported will be highlighted. Select .. to move up to the parent folder and look for the image in another folder. Press escape to cancel.

You should see the image along with a flickering border. The border represents the dimensions you set for the image. If the box is the size of or larger than the image, it will surround the edges of the image perfectly. If the image is larger than the dimensions specified, then it will be cropped to the border.

If your tile has a height larger than 200, you may get smeared pixels in your tile. The solution is to move the cursor to the top row of pixels prior to importing the image. The program imports the tile from the top row of the image, but apparently if that top row is off the screen, it takes the topmost row that is onscreen.

Sometimes, Editart will cut tall images off at the 256 pixel mark. This is most noticable when importing new sky textures. Using Editart's native copy and paste commands, you can get around this problem with a little extra work.

First, import the top half of your image. Then find an empty tile and import the bottom half. Now you must copy the bottom half of the image. Move your cursor to the top-left corner and press 1. This defines the top-left corner of the selection you wish to manipulate. Move the cursor to the bottom right corner and press 2. This defines the bottom-right corner of the selection you wish to manipulate. Now press 3 to copy the selection. This functions in a like manner to the Windows clipboard, save that the image is not stored in memory after you leave editart and is not available to other programs. Now [continued]


Animating Tiles

NoAnm (no animation) is the default setting for tiles. There are three types of animation you can apply to tiles:

  • AnmFD (animate forward) - Assuming you were creating a five-frame animation, AnmFD runs through the frames from first to last and repeats: 1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 1, 2, etc.
  • AnmBK (animate backward) - Assuming you were creating a five-frame animation, AnmBK runs through the frames from last to first and repeats (set this on the last frame of the animation): 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, 5, 4, etc.
  • Oscil (oscillating) - Assuming you were creating a five-frame animation, Oscil runs from the first frame to the last, then from the last to the first, and continues to repeat in this fashion (set on the first frame of the animation): 1, 2, 3, 4, 5, 4, 3, 2, 1, 2, 3, 4, etc.


Before you begin animating tiles, there are some limitations you should be aware of:

  • The maximum animation length is 64 tiles.
  • Tiles cannot animate across art files. For example, because your art file begins with tile 0 and ends with 255, then you wouldn't want to start a ten-frame animation on tiles 247-255, because it cannot read into

Setting the tiles to animate

Assuming you want to animate forward or oscillate, go to the first frame of the animation and press the - key. This will change the animation setting from NoAnm to Oscil to AnmFD to AnmBK. Press - until you've selected Oscil or AnmFD and then press the + key.

The + key changes the number next to the animation type, which indicates how many frames AFTER the first frame there are in the animation. If you have five frames of animation counting the first one, the animation number should be 4.

Now press A to animate it. Select Y to save it when prompted, then use the + and - keys to increase or decrease the speed of the animation. When you have found the desired speed, press Enter. Save it when you exit or select another tile and your animation is complete.

The steps for AnmBK are the same, except that you select the last frame in the animation.


Weapon Art

Replacing the art for the weapon the player is carrying can present challenges. While modern ports of Duke3D allow you to change the offset of the weapons in the con files, those who wish to simply modify the appearance of the original weapons or who are editing another Build Engine game will have to adjust the weapon alignment in Editart.

After you've replaced a frame of weapon art, press the ~ or ` key (above the Tab key and next to the 1/! key). A white cross should appear in the center of the screen. You can move the image around with the mouse and arrow keys, using the cross as a way of judging how much you've changed the alignment of the tile. If you select the pistol sprite and move its alignment down, less of it will be visible in the game. Each weapon has a different alignment, and you'll likely have to play-test it a few times before getting your new weapon art aligned properly. Note also that each successive frame must be aligned with the previous one, or the animation will be off.

Be aware of quirks in the way some of the original weapons are programmed. They may use overlapping art rather than a standard string of animating frames. Note also that there is an unused frame of animation that may be utilized in the Duke3D RPG.


Enemy & 3D Actor Graphics

Enemies and other sprites can be made to appear 3D in the Build Engine by assigning different sprites to them when when they are viewed from different angles. When you import 3D actors, you'll want to import the frames in a specific order.

You'll have to place the frames in order not only of animation, but of sides. The first frame of each part of the enemies action (standing, walking, jumping, shooting, etc.) should be the frame that has the enemy facing you. The second frame should be the same pose, but facing more to the left of the screen. There are four kinds of 3D actors, and they are named based on the "angles" value they use in the Duke3D con files:

  • 3-angles: This type uses 16 angles, but only 4 art tiles. The tiles are arranged in this order (where M means "mirrored" or "reversed") going clockwise from the front: 1M, 2M, 3M, 4M, 4, 3, 2, 1, 1M, 2M, 3M, 4M, 4, 3, 2, 1. Obviously this would only work on highly symetrical actors, and doesn't seem to be used in Duke3D.
  • 5-angles: Angles range from front to left to back in 45 degree increments. Angles that face right are created by reversing the left-facing angles: 1, 2, 3, 4, 5, 4M, 3M, 2M. Most enemies in Duke3D use this type.
  • 7-angles: Creating a smoother, more realistic look, the angles range from front to left to back in 30 degree increments: 1, 2, 3, 4, 5, 6, 7, 6M, 5M, 4M, 3M, 2M. The Duke3D rocket is an example of an actor that uses the 7-angle method.
  • 8-angles: This method is the only way to get asymmetrical 3D actors. Angles range from front to left to back to right in 45 degree increments: 1, 2, 3, 4, 5, 6, 7, 8. If Duke's creators had used this on the first boss, for example, his gun wouldn't switch hands when you looked at him from his left side.

Like weapon editing, enemy-importation sometimes requires adjusting the character's alignment. All images are centered automatically when imported, but sometimes this isn't always wanted. If you look at the Commander, you'll find he is not centered. By moving his alignment above the centerline, it gives the Commander the appearance of hovering in the game. It also seems that when an enemy shoots or spawns another sprite, the point of origin of the projectile or spawned sprite is the center-point (where the white cross's center is on the sprite in Editart).


Parallaxed Skies

Skies cannot be resized like other ceiling tiles. They follow a strict size and repeat order, and their total width always comes out to 1024. Unfortunately, Duke3D does not allow you to make skies from a single 1024 pixel-wide image. Nor will it accept skies that are 512 pixels wide. Since the sky tile must repeat and come out to 1024 pixels, its width should be a power of 2 up to 256 (1, 2, 4, 8, 16, 32, 64, 128, or 256). With sky heights, 400 is a common number among the default skies, and should work fine in all cases. (Though it may not appear to tile properly in Build/Mapster32, it will work inside the game itself.)

Duke3D uses multiple frames for some of its skies. These "panoramic skies" are made up of several images of 128 pixels in width. Panoramic skies do not simply repeat in the order they appear in Editart. Each panoramic sky has its own unique repeat pattern. You can make your own panoramic skies without having to replace the originals. You will have to mimic the repeat patterns of one of the original panoramic skies, however.


Clockwise, the sky patterns are:

  • LA Sky - 1, 3, 4, 2, 3, 2, 4, 5.
  • Moonsky - 1, 2, 1, 1, 3, 4, 1, 3.
  • Bigorbit - 1, 2, 3, 4, 1, 1, 5, 1

In order to make the new sky image work properly in your maps, you must first finish constructing the map. Place the first tile of your panoramic sky on all the areas where you wish the panoramic sky to appear, and parallax them. Now add one final sector to the map. In this sector, place the image of the sky you based your sky-pattern off of (LA Sky, Bigorbit, or Moonsky) on the ceiling and parallax it. Save your map. The game will force all of your skies to behave in the same way as the sky in the last sector placed in the map.


Complete Command List

This is the list of Editart keys and their functions from the Build Docs. The Build Docs were written by Allen H. Blum III and Richard "Levelord" Gray, with additional documentation by Kenneth Silverman. My comments are in brackets.

  • U - Use this to import a section of a 320*200*256 .BMP, .PCX, or .GIF.
  • Enter - Convert the image that is inside the rectangular selection rectangle to the BUILD palette.
  • Space - Convert the image that is inside the rectangular selection rectangle without remapping the palette.
  • P - If in the picture selecting screen (after pressing U and loading the picture), you press P, then the palette of BUILD can be replaced by the palette of the displayed picture.
  • PGUP/PGDN - Select tile to edit.
  • G - GOTO a tile by typing in the tile number.
  • S - Re-size tile. The X and Y sizes can be any unsigned short integer. X ranges from 0 to 1024, and Y ranges from 0 to 512. [my correction; originally said y max was 240]
  • Delete - short cut key to set both the X and Y sizes to 0.
  • +, - Change the animation setting. (Default: NoAnm = 0.) To change the animation type, press - when the value is 0.
    Example: If you want an object to have 4 tiles of animation, you can animate it in 4 different sequences: (0 is the current tile)

    NoAnm=4 sequence: 0,0,0,0,0,0,0,0,0,0,0,... (no animation)
    Oscis=4 sequence: 0,1,2,3,2,1,0,1,2,3,2,... (oscillate)
    AnmFD=4 sequence: 0,1,2,3,0,1,2,3,0,1,2,... (forwards)
    AnmBK=4 sequence: 0,-1,-2,-3,0,-1,-2,-3,... (backwards)
  • A - Set the animation speed of the tile. Press + and - to change the animation speed. There are 16 different animation speeds. The animation speed set here set the speed for BUILD and your GAME also. (Speed is proportional to (totalclock>>animspeed))
  • ` - This key (located just above the TAB key) allows you to center a sprite. Simply use the arrow keys to get to the desired position.
  • N - Name a tile. Naming a tile simply changes the #define statement in NAMES.H. You should include NAMES.H when compiling so you can easily refer to sprites by name rather than by number.
  • O - Optimize the size of an individual piece of artwork. Use this for tiles with invisible pixels on the sides. [also moves the cursor to the center of the tile;this makes alignment easier--simply line up the alignment cross with the cursor]
  • V - View and select a tile to edit.
  • Space - To swap 2 tiles simply press space bar on the first tile, then space bar on the second. 1,2,3 - To swap a group of tiles, press 1 on the first tile, press 2 to remember the region between where you pressed 1 and 2. Press 3 at the place to where you want to swap all the tiles.
  • ALT+U - Re-grab artwork from original pictures according to the CAPFIL.TXT file. If you press ALT-U in the main screen, everything will be re-grabbed. If you press ALT-U in 'V' mode, then you should first select the range by pressing '1' and '2' on the range boundaries.
  • ALT+R - Generate a Tile frequency report by scanning all maps in directory. Use in 'V' mode only.
  • F12 - Screen capture (saves image as a *.BMP file, starting as file name CAPTUR00.BMP and incrementing by 1 each time F12 is pressed. [also works with B key]
  • ESC - Quit.

Extra features: (if you actually want to do the artwork in EDITART or if you want to touch-up some imported art.)

  • C - Change all pixels on the tile having the same color under the graphics cursor to to selected color.
  • Arrows / Mouse - Move graphics cursor.
  • Shift + Arrows - Select color. (on bottom right corner of screen)
  • Space - Plot a pixel with the selected color.
  • T - Turn drawing trail on / off.
  • Tab - Select the color under the graphics cursor.
  • BACKSPACE - Set the color to color 255 (transparent color).
  • F - Floodfill a region with the current color and with the current color as a boundary.
  • M,P - Use M to back up a tile into a temporary buffer in memory and P to restore it. It may be wise to press M before a floodfill (F) (because sometimes you miss encapsulating the region by 1 pixel, and the whole picture gets killed, etc...)
  • J - Randomly plots dots of current color over any pixels having the same color as the color under the tile cursor.
  • [ - Random antialias of colors in color band under graphics cursor.
  • ] - Non-random antialias of colors in color band under graphics cursor.
  • ; - 3-Dimentionalize an image. Makes colors in different rows of the color bar either appear to stick out or stick in to the wall.
  • ' - 3-Dimentionalize the other way.
  • R - Rotate the tile in a specified direction.
  • 1 - Mark the first corner of a rectangle for a copy/paste operation.
  • 2 - Mark the other corner of a rectangle for a copy/paste operation.
  • 3 - Paste the selected rectangle (Note: You must press 1 and 2 in that order first before pressing 3. Pretty simple 1-2-3 for copy & paste)
  • 4 - Flip the copied rectangular region x-wise.
  • ,.<> - Change the shade of the selected region.
  • \ - Move the cursor to the center or the tile.
  • | - Get the coordinates of the cursor.


Compiling Editart

If you want to build your own version of Editart, download and install OpenWatcom, the open source version of the compiler originally used to compile Editart. Make sure you install support for DOS applications.

Open up the program's IDE and click on File, then New Project. Give your project a name. Set the target environment to DOS - 32-bit and select DOS/4GW Executable as the Image Type. Click OK.

In the project window that appears, right click and select New Source. Find your local copy of EDITART.C and add it to the project. Highlight EDITART.C and find the button labeled "Make the selected source file" (the button label appears in the status bar when you move your cursor over it) and click on it. An .obj file is generated from this. Now click the button labeled "Make the current target" to generate an .exe from the .obj file.

The IDE generates several warnings when making the source file. This is normal. If you get errors, then the program will not compile.

You will require DOS4GW.EXE in order to run your custom Editart program.  Simply install it in the same folder with your custom Editart.
