So, I know there has been no way to run gba on acekard and other carts except for some like iplayer and supercard dstwo. But I know we have home brew for os's such as linux and mac. I heard that some people were even running programs on them. Maybe perhaps you can run a mac or linux gba emulator on the homebrew and play gba games. Also on http://www.dslinux.org/ The guy says he ran desmume. I can't try it right now because I accidentally updated my 3ds to 4.3 and there is no acekard fix right now. And also there is DOS. Someone try it
EDIT: I'm kinda a noob and stuff sorry! haha
