Acekard2i is awesome.
When I first tried setting it up with AKAIO (instead of the default acekard os) it didn't work at all. I was putting in a loader, as they said to do, but not necessary with the 2i.
I setup two folders on my PC. Acekard and AKAIO. I put the appropriate files for each into the separate folders, and loaded the 4G card from the folders. Both worked great. I went with the AKAIO cause it has more features.
So far no problems at all. Everything loads great. And the card is only $13.77 from dealextreme (no ram). Can't beat that.
BTW TM, I haven't researched it much but there's a homebrew app called 3in1 or something that allows GBA roms to be played
