Hello guys, I recently bought an original Zaxxon and I found out it does not have a screen inversion switch. I don't want to mod the hardware or rotate the monitor so I found a way to modify the roms to have the screen permanently flipped as it appears in player 2 when in cocktail mode. This patch sets the screen inverted upside down when in upright mode. I tested it with 3 M.A.M.E. sets and made a tool online that you can use to automatically patch the roms, link is here -> Zaxxon Screen Inversion Patcher
