Another update on Chaos Engine. http://www.dvdflick.net/storage/disarraydevice.zip
The level viewer in the chaosspy dir has been updated with all the new stuff I've figured out. The docs describing the format have been cleaned up a bit, too. World 1 has all it's used pickup tiles added from screenshots, so their colors are a bit off. I didn't rip the tilesets originally, but the pickup tiles weren't included for some reason.
I'm still looking for the place where sprites are stored, no luck yet... levsdat.bin remains a mystery. I wish I had some 68k assembler skills!
