Most flashcarts cannot save with EMS

[Veslyquix]

Most gba flash carts only support certain methods of saving to reduce costs. As a result, only the expensive flash carts used in certain ways can actually save when fe8 hacks are played on hardware. I propose we support an alternative mode of saving to greatly increase compatibility with real hardware. Are other methods all smaller amounts of sram available? What sacrifices might need to be made?
