I just put an order in for a 256m flash advance USB linker all in one thing from liksang.com (hope they are reputable.) It cost $201 with there best shipping (4-5 day lol) I had a hard time justifying 200 bucks for what ammounts to a $25 smart media card but I've done a lot of looking this summer and that is the best price I could find on a USB all in one 256m. I just tell myself that I'll be saving 20-30 bucks every time I play a game, and I get to play EMUS on a handheld!
So what EMU's are the best for the GBA? I woudn't think MAME would be able to run on a GBA but how about NES, SMS, SNES?
What EMU's run 100% speed so far?
