i patched prince 1.0 and still have only pcspeaker sound with port interception tsr (2c0h), no sound with card listen to 0c0h, maybe there a differences in 1.0 versions ?
did this - at Offset 13875h changed 75h to EBh,
"prince tandy" gives me no sound at all.., running with port interception tsr it starts with pcspeaker sound.
stunts, eye of beholder, civilisation, maniac manison and so on works.
dune 2 does not work, simant does not work, no sound, alleycat with bjt patch, also does not give me tandy sound.
could this be a issue because i run on at machine ?
Can you try one of these games ?
Dungeon Master also is not working, because of auto detection, still have no clue how to patch this 😀
already did some disasembling but i have no clue howto find the the coresponding part in the binary file to set auto detection to all true.
