Trog (rev LA5 03/29/91)

0.34b7 [Alex Pasadyn, Zsolt Vasvari, Kurt Mahan]


Bugs:

- There are cheats that work in the memory area $20000 - $20ffff in this game, but there is no such area to choose from in the cheat engine. I thought maybe it could be a bug in the cheat engine then went to driversmidyunit.c and saw M_RANGE(0x00000000, 0x001fffff) AM_READWRITE(midyunit_vram_r, midyunit_vram_w). There is no area 0x00200000 mapped there; so how come these cheats were found? Also if you use the debugger to find data in that area, the emulator crashes. trog096u4gra Bugfinder
