I have tried to do research but I still need help. Since I own a GBA, GBA SP, GameBoy Player, Game Boy Micro, and DS Lite... I want a flash cart that can be played in all those systems. Which is a pain because I have noticed the newer ones are fitted for the DS Lites only. Since I use a Mac, I dont want it to need software and I would want it to accept clean roms. I have only owned a R4, so anything that works closely like that would be great. Easy to use, drag and drop, widely used, homebrew. Rumble is a plus but not necessary (what are there like only like 5 games that support it?) I would be a major plus if I could use the DS browser thingy with the GBA as the expansion. EZ-Flash IV seems to be my best choice but I want to make sure it will works with clean roms and that the none lite version is compatible with the DS Lite. (it is lame that the EZ-Flash IV is $30 and the EZ-FLash IV Lite is $17) If you have any other suggestions than the EZ-Flash IV. Thanks in advanced.
