I don't think there's a 100% softmod for gamecube that works without discs. I think the best is a modchip that automatically boots in the homebrew app you want. But i'm not sure, don't have a modded GC.
For Wii there are tons of apps for this if you didn't know already. But gamecube backup support is far from 100% on Wii and always without audio streams.
Thanks. I think you're correct.
The best info i found was this
QUOTEInstall GCOS 1.5 and autoboot (no menu) with Action Replay
You'll need:
A Gamecube.
An official Nintendo Memory Card, 251 or 59.
A way to run dol files on your Gamecube, like PSO1&2+BBA, or Max Drive Pro
Action Replay for Gamecube
1) ** This step will erase everything on your memory card **
Insert your Official Nintendo Memory card into Slot B.
Run "1 format.dol", press A to format it.
2) Reset your Gamecube and go into the GC bios save manager,
it should say you need to format, so format it.
3) Run "2 install-ARcodes.dol", press X to write the file,
and press R to select slot B.
4) Run "3 install-level2.dol", press X to write the file,
and press R to select slot B.
5) Run "4 install-gcos15.dol", press X to write the file,
and press R to select slot B.
6) Put in Action Replay, reset, go to Start Game, open the lid,
close the lid, and GCOS 1.5 should boot up. Enjoy!
Additional notes:
I used Max Drive Pro to run the dol files.
You need an official MC, 3rd party wont work or are temperamental.
I had to reboot in-between each step.
You might need to adjust the laser on some Cubes to read backups.
This doesn't work on the Wii, at least not for me.
Objective:
This allows you to boot Gamecube backups using an action replay and official memory card.
