DVD+RW(it's a phillips)
got it for $88 at walmart(it's a long story, but in short, one of the employees thought he was smart so he changed the price to $88 and stuck it in amongst the regular cd-rw's... I guess he was going to get it at the end of the day..... but I just so happened to be looking through the cd burners and found it.... went and found the stupidest looking clerk to check out at, and went on my way)
Me and my friend have figured out a way to copy gamecube games with it... but we have to find some ISOs.....
