Summary	07327: scyclone: Flip screen doesn't work properly on player 2 turn
Description	Before MAME 0.274: Upright mode will flip the screen in player 2 turn However, controls are correct for upright mode, as it uses player 1 controls for player 1 and 2. Cocktail mode is correct: the screen flips during p2 and its controls are p2 assigments. After MAME 0.274: It's cocktail mode that's broken now, and won't flip the screen when it's player 2 turn.
Steps To Reproduce	Start game in 2 player mode Wait until player 2 turn to see the bug

No.16444 Osso Moderator May 10, 2019, 08:49	There's a note in the driver: furthermore the game seems to set what I believe to be the 'flipscreen' bit for player 2 even when in 'upright' mode, so it's possible this romset was only really made for a cocktail table? So yes, it may be a bug or not.
No.22749 hap Developer 19 days ago edited on: 19 days ago	Either the romset is only for cocktail cabinets, or it's only for upright cabinets. Or flipscreen is determined by both vidctrl and cabinet switch, so: (m_vidctrl & 8) && !(dsw & 4). - But I'd rather not do a weird workaround like that without evidence from schematics. Anyway, I favor working 2-player upright mode over cocktail mode, so I just removed flipscreen support.
