Can you play GBA games on a R4?

My first post, ever, so be nice!Is it possible to play a GBA game on a DS via a flash card such as R4? I ask as i want to play some games but no longer posses a GBA.If not, is there some software that i can download to change my R4 so they work, or would i have to buy a new flash card.Thanks for any replies ;)

no it is not possible. but you can get an EZ Flash 3 in 1. if you have a DSi you can get the iplayer. an EZ Flash is an expansion that goes in your GBA slot. GBA roms cannot boot through a NDS flashcard so the EZ must be there so the flashcard can boot in GBA mode and play the GBA roms running on the flashcard. the iplayer is a new flashcard which uses a special SD card to play GBA roms.

no, the iplayer is a flashcart which contains a cpu and ram, allowing the DS to emulate GBA games while in NDS mode, albeit not very well. It also cannot play DS roms.

Well, The Supercard DSTwo plays GBA games.
