they most likely use advance mame/menu on there cab so how did they rotate it for there vertical orientaion.
anyone know?
thx
Very easily. I used advancemenu and one of the nice features it has is that you can rotate it ( I have a rotating monitor ). Even better it passes along the information to the emulator so that it too will rotate accordingly. I used to use advancemame itself also but my new computer doesn't work well with it so I'm using std mame and advmenu.
This is the line that does that:
emulator "mamepp" mame "mamepp.exe" "%o[,-ror,-flipx,-rol] %o[,,-flipy,]"
