I don't remember trying the older version on PSP2 specifically, but at least this works, and damn, can't remember the game felling this smooth. It however doesn't work on PSP2i, despite the similarities. I'll give it a spin before anything, but I hope that's just a adresss change between games.
Here it is. No need for the header on PPSSPP. Can be changed on the fly if you want to test.
