Ok I have a few xboxes with no dvd key so I'm getting all the nands dumped before the RGH comes out. I've come across my first jasper and read that there are 3 different kinds; 16, 256, and 512. Some of these were obviously not in their orginal case so I don't have good dates to read off the case. Is there any other way to find out which version I have or does it matter when dumping the nand?
