Without a slot 2 there's no way to run GBA games on an Acekard. iPlayer and DSTWO only can do it because they have an extra powerful CPU on the cartridge itself. NO$GBA and VBA are PC applications, and you can't run a .exe on a DS. (Even if I'm wrong about that, PC emulators can't work on a DS for the same reason any other GBA emulator can't, if I'm not mistaken)
