My main question, if I get the M3 DS and I put 100 roms on it, can I play all 100 roms and select through a list? Or can you only put 1 rom at a time on it? Because I'll get a 2GB SD card if I can put any amount of roms I want.
you can have as many roms as will fit on the card... and that wont be anywhere near 100,it will be close to 25 on a 2gb card
i have 27 roms on my 1gb Kingston card, though i use an r4ds. there is a crappy file browsing menu that i don't like so I'm programming a replacement menu for my r4ds.
