Yeah, with its "sound".Chilly Willy wrote:Good freakin' lord! Just use picodrive on a GP2X or PSP.![]()
*Sigh*. If GP2X and PSP had YM2612 inside, the emu would have perfect sound. But now having just 200/333MHz I just can't do rendering at the native rates with interpolation, accurate SSG-EG and stuff like that (unless you want it to run @ 5fps). After doing CPUs and graphics, there is not that much time left, so the MAME core is hacked in favor of speed over accuracy. While I'm updating code for the new stuff being discovered, I'm sure this won't make people like HardWareMan happy anyway, because they will still see inaccurate waves in their recordings.HardWareMan wrote: Yeah, with its "sound".
Want some help moving the YM2612 to the ME? Maybe the VP chip in VR could be done on the ME as well. That's a popular speed hack on the GP2X as well - moving the sound to the second ARM processor.notaz wrote:*Sigh*. If GP2X and PSP had YM2612 inside, the emu would have perfect sound.

How can it be credible while running like a slideshow? With skipping sound? It would be next to useless.HardWareMan wrote:The emulator must first be credible. The rest does not matter.
I intended to do that myself, but never had time for it. It could be tricky to do without killing mp3 decoding for Sega CD, which is being done using standard audiocodec lib.Chilly Willy wrote: Want some help moving the YM2612 to the ME?
What VR needs is a dynarec, I tried it on Pandora board @ 600MHz, it wouldn't reach fullspeed with interpreter there..Chilly Willy wrote: Maybe the VP chip in VR could be done on the ME as well.
I wouldn't call it popular, only 3 programs (and several demos) are using it, PicoDrive being one of them.Chilly Willy wrote: That's a popular speed hack on the GP2X as well - moving the sound to the second ARM processor.
Yes, using the mp3 audiocodec is a good use of the ME as well.notaz wrote:How can it be credible while running like a slideshow? With skipping sound? It would be next to useless.HardWareMan wrote:The emulator must first be credible. The rest does not matter.

Nice stuff! Особенно эквалайзер "Прибой Э014С", усил Амфитон и колонки "Вега 50АС106"TmEE co.(TM) wrote:I still think its best to use a Nomad
