If it is not open source, then how have we ever got any ymf262.c at all?

I still think there is no any sequencer API... but this doesn't matter for the course of this discussion, as long as the ymf262.c didn't have one either. The timer changes I did, were actually simple: when we are generating the chunk of samples, the timer may expire in the middle. Instead of delaying the timer, I split up the chunk into pieces, and update the timer at the right point. What dbadlib.c seems to have, is: - timeout detection (I've got that hack too, sad they haven't made any better) - noteon detection and a few other stream tracing things for capturing into DRO files (may not be needed as my code can capture into wav) - OPL models switching opl2/opl3 (may not be needed for sb16-only emu, as mine is) So basically I think we don't need dbadlib.c. > But yes, dosbox used to have runtime selectable OPL (MAME, Ken > Silverman, or DOSBOX), and then they dropped the (oldest) MAME one, so > it's not surprising the API is similar. Ken Silverman's adlibemu.c is stated to be 1998-2001, which might be the oldest one here. ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
