A fairly simple hack request:
Donkey Kong Country 2: Diddy's Kong Quest (SNES): Change the default sound mode to Stereo. As it is, it always reverts to Mono on each start up.
You can change hex address 0x358255 from 01 to 00 to have it default to stereo. At least, the menu displays Stereo when I do this
Okay, now this is interesting... normally the game sets the Mono flag before any audio actually plays, so the title screen music and menu music are always played in Mono (it doesn't toggle immediately in the menu.) With this change, you now hear these 2 songs in Stereo, possibly for the first time ever? But the problem is that the menu music doesn't seem to have the correct Stereo separation, and ends up sounding kind of messed up (may have to listen on headphones to really hear it.) This may be why it defaults to Mono, as a quick fix to the menu music? I guess an ideal fix would be to change it right after the menu has loaded, so that it still plays in Mono, or maybe try and fix the audio data (totally out of my league now
Last update: found a copy of the 1.1 Japanese rom, this one defaults to Stereo without needing to be patched, and the menu music sounds weird here as well. Listening a bit more closely, it sounds like in mono there is an echo on the trumpet, but in stereo, you have no echo on the right channel, and full volume echo on the left channel, so it sounds off. Might be an easy correction to anyone who's familiar with spc700 programming.
