Difference in the GCN NR lazer

"And if anyone cares, the faulty NR drive was fixed simply by tossing in a retail laser assembly, keeping the NR controller board."

I may try this with my NR Reader that wont boot any of my NR Disc..yay!

 

NR readers have in fact a different firmware on their drive board, everything else is the same. The firmware is responsible for reading the barcode, checking the leadin data ("Nintendo Game Disc" vs. "Nintendo Emulation Disc"), and does the copy protection check.

So NR readers have a different firmware, probably skipping the barcode check. I guess the data layout is still the same as on normal discs, that's why you need the NR-writer to write them.

i don't know why special NR discs are required. probably the writer checks for some pre-written stuff on it or so. or the whole DMI (which includes that "Nintendo... disc" string) is already pre-written.

 

Welcome to the boards tmbinc... good work on the cube by the way, been watching it with some interest for a while now.

 

Rofl, I didn't mean look at it as in hold a disc up to the light and look at it, I meant study it as in the scientific sense.

:die

 

Obviously. I'm just curious as its something I haven't seen before.

Thanks for shooting me down though
