Try another SD, or format it?
I don't know why it's doesn't delete it if it says it does.
I'll check the deletion code.
And it asks to copy to SD even if you already have the game on SD?
That's strange too. it should list the game on SD, not the one on USB, unless you explicitely told the loader to list only games on USB!
Settings > Loader settings > Gamecube section > Gamecube source : Auto !
(do not set only to "main path" or it will always list only the main path, not the SD path)
Originally the game was on USB and I wanted to play it from there, but when it asked to copy to SD I didn't really care. I assumed it was mandatory. The setting is also already at auto, and the SD it already at the right format. Like I said, I already copied before, just now it's being dumb.
