I started off wanting my GameCube games to run with the Dolphin core within Retroarch, but quickly realized that wasn't the way to go. I'll give that setup some time to mature. Lol.
I installed the standalone Dolphin, added the emulator to LaunchBox, made the default Dolphin association, and removed the Retroarch association.
For some reason, if I try to start a GameCube game the normal way (double-click or right-click/Play in desktop mode, selecting Play in Big Box mode) it won't load. No screen flash, no errors, just...nothing. But if I right-click Launch With, and select Dolphin from the pop-out, the game runs like a dream.
I have since deleted Dolphin from the emulator list and re-added it. Still not functioning as it should. Any suggestions?
