Idk, I have an old version of mgalaxy and dolphin (V 5).
I m using the old command line "/e" and it works without problem.
wich one dolphin version you have ?
But, I m still on old mGalaxy version.
You just made me realize the issue. I still think mGalaxy is using /e and not -e, but I'm using the latest development build of Dolphin, not the most recent stable release.
I normally go with stable releases, but decided against it for Dolphin since the last stable release was 2 1/2 years ago, which is crazy. Regardless, I'm guessing that the switch came within those 2 1/2 years and it mGalaxy definitely shouldn't be acknowledging developmental builds, no matter how old they are.
I'll just mess around with the stable build or wait until Dolphin has a new stable release and mGalaxy can then support it.
