If you're playing gen 1 or 2 on an emulator then get your shit together. Playing it on the system it was intended for is the best option. GBCs are dirt cheap on eBay, and a chimp could figure out how to replace a save battery. Even playing them on a GBA is a hassle because GB and GBC carts double the length of the system, and you're stuck with letterboxed or stretched resolutions.
