Well, I think "Flashing Hardware" is the correct term for it... Anyway, I'm pretty satisfied with my M3 DS Simply, I can use "backups" of my games on it so I don't really need to bring a bunch of game cards around everywhere. Also, the homebrew is awesome. I'm in love with PicoDrive. The video and music capabilites are awesome as well. So, how do you feel about all the flashing hardware you have?
