Ideally I am looking for something similar to the microsd method found with DS cards, where the saves are kept on the microsd, and are loaded with the game when booted. Like the Ez flash 3in 1 for DS. I currently own an old GB flashcart called "GB USB 64m smartcard", and It does the job, but is annoying to use it for more than one game at a time, since you have to rip the save from the card everytime you want to play a different game, otherwise it will get overwritten with the new games save file. This gets very tedious after a while. Also, it offers two "pages" of games that can be written to the card. To change "page" you have to turn on and turn off the handheld really quick to change the LED light on the top, which indicates it has been done. I worry that this will damage the on/off switch over time. So if there is anything available, that will be able to: >Use a microsd for storage, or something similar? >Boot GB/GBC games? >Store the GB/GBC save files on the microsd for multiple game booting? (like the Ez flash 3 in 1 DS does) I know in the topic title it says GBA, but If there is a GBC cart that does that, I'm interested too. I wont be dissapointed if one doesn't exist, I just thought I would ask to see if anybody knew of one. Thanks.
