Cocktail Flipping Available Yet?

JamesRIves

Hi all,

A couple years ago, I was thinking about using a Retropie setup with a cocktail cab I built, but then I realized the versions of MAME utilized with the Retropie build I was experimenting with didn't support the cocktail flip mode and screen rotation modes that my traditional pc version of MAME supports. I think someone mentioned there were work arounds (shaders?), but I decided to keep things simple and go with a PC-based setup.

I haven't played around with the newer versions of Retropie, but I heard it has come a long way, so I wanted to check... do any of the standard MAME packages included in the most recent version of Retropie support the cocktail flipping and screen rotation options built into PC versions of MAME?

Thanks,

Jim

Enabling flipping is just a matter of setting the cocktail dipswitch on games that support it. It's been supported for years (at least in Mame4All).

Thanks! Are the video rotation options (90 degrees, 180 degrees, etc.) also available via MAME's organic settings on a per rom basis (versus a universal modification via script modifications when the pi boots). I'd have to use both on some (but not all) games.

Fairly certain I was using AdvanceMAME on the pi when I played around with it several years ago, but as I recall, the options weren't available then. I don't think I ever experimented with Mame4all.

Thanks again!

@jamesrives per-rom rotation is supported by any libretro (lr-) mame emulator. lr-mame2003, etc.

Thanks. Looking forward to giving it a try!

Experimented last night, but I'm still having issues. My romset only works with AdvanceMame. I'm able to select cocktail mode using DIP switches, however, I don't see an option in the video settings that allow you to reorient the monitor. Is this option not available via AdvanceMame?

I solved it (sort of). It appears the option isn't available via AdvanceMame's on-screen menu, but you can force a change via including language in an .ini file for a specific game. Some additional info is available here:

@jamesrives Part of this is a misunderstanding of what the DIP switch is for. By setting the DIP, you are telling the virtual hardware that you are installing it into a cocktail cabinet. Original arcade systems did not have a button to flip the screen. They did it automatically for player 2. That is what the DIP switch does. It flips the screen for Player 2.

Note, however, that this feature is not present on every ROM. The emulation is accurate in this regard, as not all games had a cocktail cabinet mount option. To account for these, MAME devs added the flip screen feature you are referring to, so you can make the adjustment manually.

@caver01 Also, the DIP switch settings for Cocktail mode has existed in AdvanceMAME for years. I was using it in other PI solutions before trying RetroPie (what was I thinking?).
