I recently took out my old gamecube qoob pro equipped to catch up with improvements , flashed the qoob with iplboot r6 and get the SD2SP2 with Swiss r1236.
The result is absolutely stunning

I couldn't get a working IGR with this card : i tried Swiss on a different SD card Toshiba 4GB , my IGR.dol is swiss.dol renamed , i use exactly the same Swiss config as the other card, i test it with Mario kart Pal version .
With the Toshiba i reboot to Swiss, with the sandisk i reboot to the original gamecube menu.
I can't see any other difference excepting size, brand and Fat format, the Toshiba is fat32 and the Sandisk is exFat.
Do you have any ideas ?
