Well, i read about Stereo-SID the other day ; and as far as I can understand it's supposed to be able to emulate some sort of C64 configuration with two SID chips. But this is a little used option and only useful for certain SID songs created for it. No game supports it as far as I know.
So, unless this 'Stereo-SID' option in ViceX is something completely different (such as making mono sound stereo or something like that), and it does causes the mentioned issues, It may as well be axed (or fixed ofcourse).
Any opinions anyone?
Confirmed. This option is actually for stereo SID:
http://www.viceteam.org/vice_7.htmlI activated it by mistake like I was using an Amiga emulator which indeed have a "joint-stereo" option.
Anyway, the C64 SID chip has one output pin unlike the Amiga Paula chip that has two. So nothing to do with stereo, here.
But I may try some Stereo SID demos just to check how this feature behaves on the xbox. Though it's irrelevant for gaming.
