My goal is to be able to play GBA and NDS ROMs on my DS, including the needed RAM for opera, and i have recently been looking though reviews and many sites to try to find just that. Over my course of looking, to me it looks like the Acekard R.P.G might be the best choice for Slot-1, but finding the Slot-2 device to allow me to play GBA ROMs has been hard, The only ones that even look promising are the M3 DS Real GBA Expansion Pack and the EZ 3 in 1 Expansion Pack. I am really looking to see if the Acekard R.P.G. is a good choice and which Expansion Pack out there is the best for extra RAM and playing GBA games. Thanks Another quick question, in all the reviews for the Slot-2 device to play GBA ROMs they always comment about how you can only have 1 GBA ROM at a time on the Expansion Pack and that it takes a long time to copy the GBA ROM from Slot-1 to Slot-2. For the last part couldn't there be a way to make a Slot-2 device that had a MicroSD slot and have the GBA ROMs stored on there, making it faster because you wouldn't need to transfer the ROM? Are there any out there like my idea? Could you use on of the older Slot-2, Ones that have a MicroSD and made to boot on there own like the M3 perfect, to be able to play GBA games though Slot-1?
