Within the last 24 hours I've been looking at the whole portable back up scene. Quite frankly, it's fascinating. I'd like to back up everything I own, now let me get this straight... So far I've been looking at EZ Flash IV for a slot 2 device for all my GBA games. Am I right in saying it's easy to emulate GBC on it (or similar device) so that once backed up, I could ditch my GBA as all will play on DS? HOWEVER... I have also seen EZ Flash V, which would be great for all DS stuff and the 3-in-1 expansion also looks great as an alternative to EZ Flash IV (although I really fancied a perfect colour match as the EZ Flash IV has with the DS Lite white, apparently). Are there any distinct advantages over the 3-in-1 expansion that the EZ Flash IV has? Are there alternatives to the 3-in1? Are there any slot 1 alternatives to EZ Flash V? Are multiple games possible on an EZ Flash V? How big do micro SD cards go? Reliable brands? There is loads of stuff I don't know about so if there are more up to date products, etc. please let me know!
