mame help

how can I turn a horizontal game to a vertical game

If you are running a command line MAME, add " -ror" or " -rol" to your execution command.

ex: mame joust -ror

this will run joust but rotated to the right.

If you have a GUI-based MAME like MAME32, just open up the MAME32 and find the romname, right click on it, and it will show you several tabs. Look for the one that lets you specify the screen orientation and set it to which ever way you want to rotate the screen.
 
As said above, yes you can alter the screen position via the Tab key options when a game is running. But there's another way.

If you are using MAME32 or similar, there should be a setting in options where you can designate "rotate screen" - look in Preferences or Options for this. It will only affect specific games.

Tell us if it works.
