Names of the relevent GC kit, star wars dev video and some other websites for info.
DDH = Dolphin Development Hardware
NR = Nintendo Reader Debug console (Green)
NPDP = Cartridge based debug console (red)
GOD = GameCube Optical Disc
GC-R for developers beta disks (no bar code)
GC-ROM for final production disks (bar code present)
I've now modified my GC more than before. My 'cotton' swap trick method means i can hold in the lid
detecion switches from outside and swap as normal.
observing the laser mechanism with the lid open and some cotton holding the lid detect switches
down let me see where the disk was reading.
There are at 2 checks for the system setting. Once to setup the bios menus etc
but if i change my switch after bootup i can put in a JP disk and it will come up with corrupted fonts!
it will load however
I've swapped disks with a GC-R i got and not had much luck there, the system bios puts up an error msg
in japanese saying turn of the power and read the user guide as the disk is not recognised.
As soon as the disk is inserted the bar code is read, then after that sucessfully completes the disk is
loaded, with the tracks starting in the centre and working out.
waverace has the audio track streamed, the track is on the outside of the disk as you can see which area
it is accessing.
as the check is only done once if that can be faked a homebrew min-dvd-r disk could be booted.

I'm sometimes getting a discid of 02176D01 from the disks, which does not mean much to me.
I'm geting wildly variying framesizes [1 LBA (Logical Block Address) = 1 Frame]
between 72bytes -> 1,684,828,002 bytes sometimes
if anyone else out there has managed to read a disk with linux or windows you can contact me at
atari@anarchists.co.uk
dd if=/dev/hdc of=/root/rip.bin bs=512 count=512 conv=noerror
or use clonecd in windows if your that way inclined.
