The only other possible way I could see that "Even the main MAME menus are rotated to the left. " is if he started the game with "-rol" (rotate left). If he attempted to rotate it back in menu, shut down the game and restart it with "-rol" again - the game would be upright but the menu would still be rotated.
Clear out the tempest.cfg or .ini and make sure you are not sending and rotate screen commands.
