I meant Amiga DOS obviously, not MSDOS.
I uploaded a new version of the source code with a ll subsidiaries exe disassembled and their data extracted, so the disassembling itself is now finished.
The gfx are in Amiga bitplanes raw format, most of the palettes are located in the various .asm.
I may do a remake of that game for the PSP, i was in for a Tower Assault one but SE will do just as well.
Btw, it's interesting to note that the code and data files feature 13 levels while there's only 12 officially, i don't know where the 13th one is gone.
Also in the menu exe there was some code for an option to let the players select different characters (maybe with different abilities), obviously they scrapped that idea before releasing the game.
Edit: And i just noticed there's a PC remake of ABSE here:
