Well that does bring up a few questions...
How is the yaubuse performance on the PSP?
How is the compatibility in yaubuse?
I've seen dynamic cores really speed things up so you'd be surprised.. But the Saturn was like a mish mash of different processors. Just think 32x times 5..
I can only find a few videos on youtube. Some run smooth, others are quite slow.
The other problem is that yabause hasn't had much activity lately (maybe dead).
The PSP porting author said that he designed the recompiler to be portable to other target architectures. He also has in mind some other possible optimizations since the actual SH2 compiler is in fact a Mips compiler instead. If you ask him kindly he might reply to performance/compatibility questions as well.
Another interesting point is that mame is currently developing a "universal dynamic recompiler". Don't know if it could be re-used for all the Saturn CPUs (at least SH2 and 68K).
