Hi, I have a GBA bought about 6 years ago and now I gave it to my younger brother. Now I need a flashcart for it but I can't find any. The recommended ones I found here were EZFlash IV and Supercard. In the sub-Supercard products, can you recommend any? And the site from where I can buy 'em?\ I have a DSi too. Is it worth buying the SupercardDSTwo for playing GBA games on it? I've heard it eats up the battery pretty fast through its CPU. Thanks.
