ok, CD-Rs and crap that are not GD-ROM format harm the laser a little right? well, since you NEED to use CD-Rs for emus and ROMs on DC, and since the CD-R needs to be in at all times that you play this will really screw the laser up right? how much will it shorten the life of the drive? BTW, which is the best Genesis emulator on DC? SNES? NES? SMS?
