I have a lot of interest in investing in a device that has great emulation support for older systems such as the GBA, GBC, GB, SNES and NES. Obviously some obvious choices would be those original systems or the PC but when I am using the computer I usually don't play with emulators and stuff. What are some good portable devices that can emulate some of these systems well enough that I can play most of the big titles of them? I know the DS doesn't have GBA emulation unless you use a slot 2 device or that expansion pack thing. Whatabout its emulation for the other systems? I used SNEmulDS and it doesn't seem to run a lot of games smoothly... Yea I want your input guys!! Is the PSP a good choice for emulating those older systems? Maybe an iPod Touch!? The Nokia N810?
