if someone were to find an appropriate way to use the arm chip in the DC, we could have full speed gba using that (before anyone says the bus is too slow, think about its speed not relative to the rest of the DC, but to that of a gba.)
as for playstation, i think it could go up to around 20fps without using asm which, with frameskip would be playable (barely?).
There have been no sh4asm advances made, and we have yet to see anything benefitting for sh4 recently (the dsnes core was old AND it could be argued that SFC was better without it, since it got faster without sound than it can at all with the new core), and FAME has yet to be added into anything, so we dont even know if it works.
I think a dynarec core for PSX might make a large difference, but that could simply be the musings of a madman.
