MAME mode Cocktail

phulshof

@phulshof That's pretty sweet. So Mame can do this and remember the settings for all games that supports it or can this be done with all Mame games on a cocktail cabinet?

I set this up as a generic overlay, automatically selected between horizontal and vertical mode for all games (where I used single player setup as default for vertical); you can also select the overlay via the -view parameter in MAME. Biggest problem is that I haven't been able to convince MAME to accept generic overlays via the normal artwork directory (not sure if it can be done), so I had to add them to the MAME source code before compiling. MAME already contains horizontal and vertical .lay files, so it was simply a matter of changing them, and then compile. If anyone knows how to set them up as generic overlays without compiling them in I'd be much obliged. :)

This should work just fine for almost all games; it's just multi-screen games like Darius that need special attention.

I just had a chat on the MAME forums; seems like the only way for now is to compile it in. I'll see if I can create a patch for the code to allow it to be done on the fly using the artwork directory, but there's some tricky issues with multi screen games that I need to keep in mind when doing this. It'll take me a while to find enough spare time. :)

The video mirroring can definitely be a useful effect for some cabinets, but it is not cocktail mode in the traditional sense. I expect this is most useful on games that have simultaneous multiplayer that would normally be side-by-side but on cocktail cabinets that have their controls oriented head-to-head.

that split screen thing can be achieved in any libretro core via a shader. https://retropie.org.uk/forum/topic/6287/mirrored-cocktail-mode/3

Seems like I have generic overlays working now; I'll do a lot more testing to make sure I didn't break anything, and then offer a patch to the MAME team. This could prove to be quite useful. :)

I have just spent 4 hours changing hundreds of dip switch settings to cocktail mode. only to discover it doesnt save it once rebooted.
Anyone know how to save this.
Actually, just noticed it saved the settings for donkey kong but nothing else.

@robthedude81 what emulator? I use lr-mame2003 mostly and I have no problems. AdvanceMAME also saves this setting per rom.

@caver01 I was using mame2010 i m just testing with 2003 and not all the games work but its savingthe cocktail mode for the games i want anyway

Thanks

@robthedude81 what do you mean not all the games work? Are you using the correct romset (0.78)? The ROMs for 2010 and 2003 are not interchangeable. Also, not all games had a cocktail mode. This only works if the original hardware supported it.

All I want is no enable them in the mame2000 libretro core..but I'm under the impression that that ability is not in the 2000 core. The 2003 core is too slow on my rasp pi B+. And forget advance mame on it. lol Advance MAME has a hot key to "flip on demand". Good for games that are cocktail..but MAME doesn't support the flipping in the code itself for that rom.

Speaking of cocktail tables do I want three or four buttons on my cab when I make it?

This depends on the games you want to play. Make a list of your favorites, then google images of the original arcade cabinet control panels and count the buttons. You will quickly realize there are games you can or cannot play with a given number of buttons. Then, you just have to decide if you can live without a game.

Keep in mind you probably also need START and COIN buttons for each player and maybe some admin buttons.

Hello hope everyone is doing good , I am trying to put together an arcade cocktail and from my failed attempts this forum has definitely inspired me that it can be done , I made one before using h.s but I wanted to make it more portable so I wanted to use mameufx roms that I already have 200 of them or less , but I don't know where to beging I found an image on YouTube where the pi loads right into the vids and you scroll thru it but when I tried that image it would scroll halfway and get stuck then freeze , and I tried several several several times to do it from scratch but iam all new to this so I suck at it I was hoping is there any one that has finished theirs , that can help me put together mines , thank you all for your time and help .

@rijosroberto you need to use the official image or nobody can help you. Then, you need to use a romset that matches the version of MAME you want to use. Read the docs, especially the arcade and MAME sections.

@caver01 thank you , currently I have installed the image from the pi website and I have it on attract mode , but attract mode isn't picking up the roms that are in there ,
