Image Files

All image files are uncompressed with one byte per pixel. Each byte is an index into an EGA color palette. The image dimensions are not stored in the file itself. The bytes are in row major format, so each pixel is addressed as [y][x], that is y is the first index.

Program to Decipher Files

This GitHub repo contains a program called con2png. It's a command-line program that takes any of the following image files, along with a palette and dimensions, and produces a PNG.

.CON Files
These files are sprite sheets for enemies, tiles, player graphics, and spell effects. Each sprite is 18x18, and each sprite sheet lays these sprites out horizontally.

The following files are tile sheets, used as the background layer for maps. There are 20 sprites per sheet, which makes the final image 360x18. Which tiles animate vary between maps.
 * AFTER.CON: The tile sheet used in Heaven. The brazier is animated.
 * DUNGEON.CON: The tile sheet used in the Blackeye's dungeon, the Talisman dungeon, the forest ruins, the mountain ruins, and Vampyr's Castle
 * LAND.CON: Additional tiles used to supplement UNIV.CON on the overworld.
 * THEEND.CON: The tile sheet used during the ending sequence.
 * TOWN.CON: The tile sheet used for every town in the game (including the castle).

TITLE.00[1-6]
These images, when stitched together, form the background of the title screen. They are laid out as follows: Each individual image is 106x99 pixels. Stitched together, this makes an image of dimensions 318x198 pixels (close enough to 320x200, a multiple of the actual game resolution of 640x400).

SCROLL.PIC and MSCROLL.PIC
SCROLL.PIC is the poem that appears during the startup animation. It is 290x77 pixels. This image is reused for the main menu background by overwriting the black pixels with the patterned fill. The writing on the scroll, according to the EGA color palette, should be purple.

MSCROLL.PIC is the end-scroll that appears to the right of SCROLL.PIC. It is 25x77 pixels.

ITEM.00[1-7]
These are various icons that appear in different places on the main menu. Each icon is 25x25 pixels.
