would lower sample rate help?

(i suppose this could be considered a suggestion/request for the next release)
what sample rate is the sound being played at in dreamsnes? snes9x has an option to play at different sample rates.... just a thought. i wouldn't mind playing my games at 11hz mono

and what's up with all these people saying Chrono Trigger runs at 95%? i'd guess 93% is more like it. (lol i'm joking)

well anyway... *goes to a blank item screen to listen to the music closer to full speed* ahhhhhh *sighs in relief*

I don't know if it is the sample rate of the audio causing the sluggish sound you describe, I think it's due to the fact the SNES sound CPU is a pain in the ass to emulate properly and speedily-- which probably explains why the mono sound option in DSNES speeds up a lot of games, like Metroid.

Well if you think about it, the emu usually runs full speed with sound off and doesn't when you have sound off. 0.95 has an assembly graphics core so it makes sense that the sound core isn't assembly. Perhaps when the sound core is assembly then 100% speed will be attained.

well not trying to kill your dreams here, but regex wrote an optimised asm sound core for frnes and it made almost no differance... he went back and wrote other parts in asm to make a speedup, but with the core of dreamsnes already asm, i dont think there is much more that could be done for speed except maybe a faster graphics renderer or maybe putting sound onto one of the other chips so it doesnt put a load on the cpu...

if there was a sample rate selection, having worse quality sound would improve speed a lot. playin with 11khz would be near the speed of having no sound.... i dont mind using a low sound quality as long as i got good speed and sound

i hope they add this feature.

I'd say the bitrate of dreamsnes was 22khz but im not sure.

they tried to make the ARM chip do that but it sucked(which is why 0.9.5 wasnt released for christmas)

zah :(

how discouraging
