Finally got Super Mario 3D All-Stars installed
Using the homebrew app that installs gamecards.
Apparently, if the sysNAND is too low, the GC firmware won’t be able to read the gamecard. You could turn off the blocking of GC firmware updating, but then no reading games in sysNAND either.
Glad mine isn’t patched.
I’m too lazy to back it up, copy to computer, then install the file. It’ll be a bummer if the SD card dies, and the gamecard gets lost. There is another solution, backup the micro SD card.
