So far this seems all quite bad to overview... so maybe we can make a short list here, about which options you have for real gba cartridges (which also work in a normal gba): I just know the ELINK, the EFA and Super Card. I already ordered the Elink, so at the moment I'm set, but I might buy another one in some time... Then I've heard about EZ4 etc. but I think that is just for the Nintendo DS, or how is that? Is there any of those (said to be better than others) ezflash cards for just the GBA? For not too much money... (maybe from DX ?) I just don't get which are GBA ... and which are GBA-games but just on NDS ? Thanks in advance for making some things clearer!
