I just got my wife a DS Lite. I've been reading through the forums trying to get the necessary info. Seems pretty basic... get a cart, get the firmware, play your backups. So my first job is to choose a flash cart. It seems the M3 DS Simply is the most popular choice followed closely by the R4. Both require external memory. The DS Xtreme and G6 DS Real has on board memory. Money isn't an problem. This NDS is all new to me and I can seem to find any related articles, so, can anyone give me any pro/cons of using one cart over the other? Thanks guys.
