well I decided to just commit what I have, its very basic and might not for you, also make sure to enable memcard emulation if you want to have a chance of it working at all.
-added gamecube bios support, please note that this is still very early in testing so it might not fully work, to let a game start using the original gamecube bios place iplusa.bin, ipljap.bin and/or iplpal.bin onto your device root, if nintendont finds the bios fitting to the game region it tries to start it, as of right now this feature has no use whatsoever and only exists for pure demonstration purposes
How does it work with the memory card emulation? If we have MULTI turned on does it show all our save files?
