I'm thinking about getting a PSP an had a question about the emulation. If I want to play GBA and SNES games, do I need to be running a CFW? Also, I know that SNES emu is iffy at best, but how does GBA emulation perform? Also, do I need to use a CFW to play any PSP games that I get off the net. (In fact, is that even possible, even with a CFW?)
Yes, you do need a custom firmware (or firmware 1.50) to run emulators.
GBA emulation, iirc, is very good, with nearly full speed, sound, graphics, etc.
And yes, with a CFW, you can play PSP ISOs that you download from the internet.
