This is just a thought, I know stuff all about programing so please don't go mad if i am talking from my behind here, but:

zx-81 you said:

GBA -> 32-bit 16.8-MHz ARM
NeoGeo -> 16 bits 12 MHz 68000
Snes -> 16-bits 4 MHz

The PSP is max 333Mhz.

Generally to emulate properly a processor you need multiply the frequency by 25, and it gives you the required frequency for the host processor. Here, 12 * 25 > 300 Mhz, so we can emulate a SNES or NeoGeo.

But for GBA : 16 * 25 > 400 Mhz, so we can see that it will be theoretically very hard to emulate a 32 bits / 16 Mhz ARM processor on a PSP ...

BUT.........

Sony is planning a PSone emulator, and that had a processor with a clockspeed of 33.8688Mhz, so how is that going to be possible when emulating a 16Mhz GBA processor is so hard??

Not being critical, just wondered.

Because they don't do software emulation, but re-compile the PSone games on PSP plateform
