Sad to see that link rot is starting to set in with many of the projects that I mentioned above. For example, the SNES emulator:
I sold it off when I got a smartphone, but I do miss that PSP from time to time.
I didn't pick up a PSP-1000 until maybe two years after it came out? Emulation on that was fantastic, minus the ghosting on the screen. It's still one of my favourite ways to play Sega Genesis games on the go, and even handled GBA titles like a champ.
