I've begun to port most of my emulators mainly written for fw1.5 to fw3.x and psp slim.
I haven't got any psp slim myself, so i'm looking for someone kind enough to help me for testing.
I've finished to modify psp2600, pspint, psp7800 and pspcolem, but i need to be sure they will work on psp slim using custom firmware before to release them officialy.
If you want to help me, please post on this thread i will send you a pm. I don't need many person, only one is enough.
