Listen guys, sorry to be a pain in the ass but I was wondering if you could help me out....

I've managed to get xmugen up and running, but only in a green screen. I get that this is a video mode problem, but am out of ideas when it comes to fixing it! I've tried several different versions and the result is always the same.  The Linux boots through in green lettering and i get a green title/character select screen.

Not sure what my xbox version is, but im running it through a HD tv with a bog standard SCART cable (my component sockets are taken up by my 360)

I've tried fiddling with video settings in mugenboot.cfg and mugen.cfg, to no avail.  I did try searching for linuxboot.cfg, because a couple of forum users have mentioned it in passing, but i don't have it. 

Surley there's a way to fix this anoying gripe without me buying new cables and switching them round when i want to switch consoles? Just some setting I've missed?

I've googled my ass off and you're are my last hope.

Thanks

Chris
