Doom8088 Save

Doom8088

Doom was originally designed in 1993 for 32-bit DOS computers with 4 MB of RAM. It's mostly written in C code with very little assembly code. It has been ported to all kinds of systems. Usually these systems are 32-bit or more and have a flat memory model.

Doom8088 is a port for PCs with a 16-bit processor like an 8088 or a 286, and with VGA or MCGA graphics. It uses 64 kB of EMS memory, if available. It's based on GBADoom. Download Doom8088 here.

Building:

1. Install gcc-ia16 (including libi86) and NASM on Ubuntu.

2. Run compiamy.sh to compile the Mode Y version and compia13.sh for the Mode 13h version.

3. (Optional) Compress DOOM8088.EXE with LZEXE, just like all the other 16-bit id Software games.

4. Doom8088 needs an IWAD file that has been preprocessed by GbaWadUtil. Some lumps in the WAD need to be replaced by the raw images from the WAD directory in this repository. In addition, some manual actions are required. It is best to just use the IWAD of the latest release.

It's possible to build a 32-bit version of Doom8088 with DJGPP and Watcom. First run setenvdj.bat once and then compdj.bat for DJGPP, and setenvwc.bat followed by compwc32.bat for Watcom. For debugging purposes, the Zone memory can be increased significantly this way.

It's also possible to build a 16-bit version with Watcom: Run setenvwc.bat followed by compwc16.bat.
