Several new details have come out about the 3DS recently through various sources. Luckily the fantastic Tiny Cartridge has compiled the 2 biggest ones together for us. First of all in an australian preview of the system you can see that standard DS games can make use of the Circle pad and the way that it scales the games as if they were on a normal DS. Ill link that after the jump
Also IGN had an interview with Nintendo where it was revealed that some companies could offer the ability to use Custom Soundtracks on the DS by uploading MP3’s onto the system through an SD card. This is pretty neat since sometimes when your grinding in Dragon Quest you just want some different music.
