[jjmaia]

Hello there.

I've bought and GBA SP (been locking for ages because of the back light) and so i don't i have to use cart's i need a flashcard, and i would want you opinion.
Something good, reliable, and that would play not only GBA, but also Gb e GBC. Real time save would be cool!

I have an Acekard for my DS and i am very satisfied.

Thank you for your help.

You will want to skip anything that says lite, or if you want to try carving a shell to hold a lite version of any of the flashcarts listed.
