I too have had a GP2X since launch and I still have my GP32.
Great little emulator/homebrew systems.
Sadly A500 emulation is not fantastic, but understandable as it is one of the tougher systems to emulate accurately and with good speed. Also critical the developer and man responsible for the GP2X port of UAE4ALL has left the GP2X for the gizmondo scene porting many emulators for that system instead.
CaSTaway the *spit* AtariST emulator is great though pretty much full speed with not bad sound.
NeoGeo and Mame are awesome and many 8-bit systems are covered. I highly recomend one to anyone with a passion for retro systems and emulation. Most of the emulators out perform the more powerfull PSP (Amiga included).
