Hey guys, I've had a look around awhile I'm sure the answer is buried in here somewhere but I can't seem to find it so I thought it easier to ask. I'm in need of a memory expansion for slot2 and was wondering if I would be able to use my GBA flash cart 'flash2advance ultra 1g' or if I would have to purchase a 3 in 1. I haven't found any info on the subject which makes me think I probably won't be getting away with my old cart, but if I can that would sure save me a little bit of time and money so any feedback is much appreciated.
