recluse, are you entirely sure, that our current (for Fremantle) emulator uses/should use GPU?not that it's impossible, but after all, it's emulator, those tends to run on CPU, mainly (thus all fuss about Just-in-time compiler, etc).

AapoRantalainen, any comment on this, from perspective of someone who brought it for us?

When you're emulating a console that has a GPU, it is essential to use your GPU to replicate the display queue.
Areas that GPUs excel at are obviously very hard for CPUs to emulate (often up to a tenth of the speed).
The use of GPUs in modern consoles have allowed us to have amazing graphics and special effects. Realistically you would need an incredibly fast multi-core processor to simulate these effects.

Some emulators are just lazy. Especially for consoles that have weak hardware and are easy to emulate. Also, it's only recently (4-5 years) that mobile GPUs had a decent GL API (GLES 2.0). Before that, we couldn't run shaders on mobile for eg. I suspect that's why no one ever made a GPU plugin for PSX (GLES 1.0 doesn't count).

Definitely with PSP (PPSSPP) and Gamecube/Wii (Dolphin), the GPU is taken to maximum advantage in order to get playable results on weak hardware.
Without this, PSP and Gamecube/Wii would not be possible on mobile devices.
