Vertical cocktail mode help

[Giddygoon]

Hi All,

I've just finished a groovymame cocktail cab which is running GM 161 running a bunch of vertical games like moon cresta, galaga, bomb jack, I just set the games to screen 0 display 3.4 and set the dips to cocktail screen flip mode

But when I turn the cab off and switch it back on it doesn't show single screen 0 in 3.4 mode but I have the game displayed twice split screen

I already tried numscreans 2 on each of the ini files ( btw my ini folder is clear but just these files with numscrean 2 )

But I still get the same problem... I can set it in game via video settings but it reverts back to split screen ( game twice on screen )

Please help.... What should I put in the INI folder to stop this

Thanks for any help
