I want to get a flash cart to play some old pokemon games with a gba emulator. The only one that looks any good though is the DSTwo. What I want to know is, can I transfer pokemon from the gba to the ds save files with the DSTwo or do I need a slot 2 cart for that. I read somewhere that the DSTwo has something called gba extend which would allow this but I'm not sure if I also need something like the EZ-flash IV or EZ Flash 3 in 1 expansion pack to do this. And if I can't do this I guess I'll have to get either the EZ Flash IV or the EZ Flash 3 in 1 expansion with my r4i. Any help would be much appreciated.
