I'm really interested in getting a GBA flashcart to play GBA games on my GBA SP. Now I've heard the absolute best is the EZ Falsh but I also heard it still has limitations. One of the biggest being the no internal clock thing... Will this play on my SP? So my question is what games won't play because of this issue? Any other games that are simply not compatible? Is there any cart with an internal clock? Or a way to install an internal clock in it (highly doubt it but want the thought out of my mind)?
