I already have an EZFA cart for playing GBA. I basically want the equivalent of it only with a micro SD because my EZFA has only 32MB storage, like most of the flash carts from back then. Basically my EZFA includes: *real time clock *works with every game I ever played from Advance Wars to Riviera. *the client included auto trimming, and patching for cheats and soft reset *normal GBA cart size for a DS classic It sounds like the EZ4 is popular, but lacks the real time clock so I'm not sure which one I need. Plus it seems difficult to find a site that sells the normal in addition to the lites. And I do not care about DS games compatibility whatsoever, I already own an Acekard RPG so for all I care, my GBA cart should only play GBA games.
