Shiranui-san: I suppose it's with r1215?
when did it happen? in a particular menu, or when booting the loader? did it finally work on the 5th try?
more information is always welcome when you report a bug
Bryon15:
1. be sure to use r1215, it's the latest revision available publicly (look in the credit page to be sure you are using the correct revision)
2. Click on the 4th icon in the top menu, and enable GameCube
3. Put the games in SD or USB;/games/
SUBFOLDER HERE/
game.iso
the filename MUST be named "game.iso" (not the game name, the 4 letters g+a+m+e)
The subfolder is require in USBloaderGX, or else it will not detect the ISO. that folder is better named after the game name and gameID, for example games/Legend of Zelda [GZLP01]/game.iso
4. you should have SD;/apps/gc_devo/loader.bin and in the loader's "user path" menu, the "Devolution folder" should be "apps/gc_devo/"
If it still doesn't display the games:
5. Force games listing from USB only or SD only (instead of AUTO), by going into settings > loader settings > GameCube origin : Auto/SD/USB.
Information:
6. Go to User paths:
There are two "gamecube path" : "Main" and "SD".
The "Main GameCube Path" is the one used when you dump a Disc using the loader, the ISO will go into this folder. it's best to put it on an USB device if you need to dump more games than your SD can hold.
The "SD path" is used as the place where the ISO are copied to if you use DIOS MIOS Lite to launch gamecube games. (as only SD can be used, it will copy the ISO from USB to SD before launching the game).
Check that your "Main GameCube Path" is set to USBx:/games/ (x= partition number)
there is also a "SD gamecube Path", this one should stay on SD card.
Of course, if you are using Devolution, you don't need to transfer the ISO to SD, it will launch the game from the place it's currently stored.
If you have the game in both SD and USB, it will only list one game.
Select the device to display in "GameCube origin" setting.
If it's set to "auto" it will depend on the installed MIOS (DIOS MIOS = prioritize USB games, then SD. DIOS MIOS LIte = prioritize SD games, then USB)
