I have a GBA SP that lives in my bag, with an old XG2 Turbo 512M (must be at least 6 years old, maybe) living inside it that I'll update with new games very occasionally. Compatibility is great for most games, except since it doesn't get played that often saves never work - they've never been great on it anyway... I'm after a cart I can leave in the SP safe in the knowledge that saves will be fine the next time it gets powered on - even if this is once every six months. Just wondering if anyone knows what cart is (a) GBA cart sized. Must not stick out at all. And (b) retains saves irregardless of battery in cart or GBA. It'd be be a real bonus if it didn't need any special software to load stuff on and has a non-crap menu but these aren't critical. I just want something I can shove half a dozen to a dozen games on and leave Any suggestions?
