Flip screen on cocktail mode

[dagareux]

With the current setting, cocktail games are not flipped to player 2 despite checking the dip switch cabinet setting to "cocktail".

We don't support cocktail mode, and while some games have their cocktail mode working and we might consider fixing a few more if they are easily fixable, you'd first have to name the game(s).

A little insight as to how it works:
These days, coctail mode is the only way to get 2 joysticks w/2player mode in older games,
in a lot these games, we unflip the cocktail mode so they can be played via netplay - as is so commonly done now-a-days.

If you're actually running a cocktail cabinet, I can only recommend using MAME at this time, because they support normal
cocktail flipping in most games.

Another option would be to add an option to fbneo to enable/disable cocktail flipping. This won't be too easy as it sounds, though. A lot of drivers would need small modifications to allow for such an option.

Hi, thanks for your feedback! I don't use MAME as many games don't launch properly hence one of the reasons I migrated to fbneo. Also, I tried to configure cocktail mode on a few games and it wouldn't work either despite configuring the different MAME cores. I have a cocktail cabinet so it would be cool if you could code a bunch of cocktail games. I believe the list below is the complete one (I've marked the ones in bold that I'd like to see coded):

1942
Arkanoid
Astro Invader
Baby Pac Man
Burger Time
Centipede
Crush
Dig Dug
Donkey Kong
Donkey Kong Jr
Donkey Kong 3
Frogger
Galaga
Galaga 3
Galaxian
Gorf
Gunsmoke
Gyruss
Ladybug
Mappy
Millipede
Missle Command
Mr Do
Mr. Do's Castle
Ms Pacman
New Rally X
Pacman
Pacman JR
Pengo
Pheonix
Qix
Robotron
Scramble
Space Invaders
Super Breakout
Super Cobra
Super Pac Man
Tempest
Tank Battalion
Time Pilot
Xevious
Zaxxon

@dinkc64 I had totally forgotten about those games that only allowed 2p in cocktail mode.
Thinking out loud, if we really wanted to have both a flipped and an unflipped cocktail mode, maybe one of the 2 modes could be handled by calling a function causing a blitter rotation instead of messing too much with the driver's code, kind of like how Reinitialise is used for changing resolution.

@dagareux I'm pretty certain you are not talking about the current version of MAME.
Obviously if you are using a MAME version from several decades ago, you'll have a lot more bugs.
