Killer Instinct/Mameox boot problems

[weezee]

I don't know if mameox works exactly like the pc version, but here we go:

zipped roms must be inside \roms
UNZIPPED CHD files must be inside \roms\gamename\

where gamename is the name of the CHD.

So you should have something like

\roms\ki.zip (the small rom file)
\roms\ki\ki.chd (the big HD image)

Xbox ram is not an issue, since Mame should load from CHD only the levels you are playing, not the entire CHD.
This happens only if you zip the CHD, which is not a smart move.

I suppose this is ok on both PC and XBOX.
