First off, sorry to bring back an old thread that will prolly make some peeps go "ah no, not again!" lol
I had this mugen 4.9 for F drive running like a charm for 2 years now.
The xbox in question is inside a PC case from an old mod, and I decided to make an arcade cab with a different xbox and COPY over the same folder to the SAME place in the other xbox.
Both same xbox 1.3
Both same chip smartxx v2
Both in the same place F:/emulators/xmugen
I literally copied from xbox to xbox to make sure I had the same setup.
It STILL boots on the first one, but the second I get this error.

I tried everything and have been reading for 2 days on this 30 page thread. I just dont get it.
It cant be the setup, it works on one xbox.
any input would be greatly appreciated.
thanks

Did you make sure the Linux Config file is in the root of the drive and that it looks correct?
also, are you using a controller other than a official Xbox controller? That could cause an error too.
I got that error before from these issues.
