Extra Buttons (Esc., Pause, etc.) for MAME Cab
maraxle:
On mine, all I've got is an exit button. The coin returns are setup to register a credit, eliminating the need for coin buttons. As for the LEDs, you could just get some bigger ones at Radio Shack (or similar) and mount them wherever you want.

"Standard" LED's are 2.3 V, but I don't know what the PC is using. Also, even if they are 12V, the circuit to the LED's might not supply enough current for a 12V lamp. You could use a relay, I suppose.

I'm not planning to use a workaround, but there are 3 things you could try (4 but one won't work) -
1) You could use the Shift function of the encoder, but I don't like this because you have to remember a key combination for each function.
2) Doesn't work - I thought you could set MAME so both Coin and Start 2 are mapped to "2" for these games. Then pressing Start 2 initially will add a coin, pressing it again start the game, oops, just tested it, it doesn't work - MAME just keeps adding credits and doesn't ever start the game.
3) For some of these games, TMNT for one, the game uses Button1 as the start button. I planned to map this so P1B1 was "1 or L Ctrl" for this game so it appeared to work like all the other games, but you could do the opposite (I tested it) - Map Coin 2 to "2" in MAME, then press P2 Start to add P2 Coins, and P2B1 to start the game. I don't know if Gauntlet, Desert Wars, Quartet and the other "Coin 2" games will work with this method or not.
4) Almost all of the games that needed dedicated Coin 2 buttons were 2 or 3 button games, so you could map Coin 2 in MAME to P2B6 (K ?) for this games and press P2B6 when you wanted to add a Player 2 coin. Confusing for a new person using your cab, though.

Tab - set inputs and or adjust dipswitches
Enter - When you start a game and it says "Press select key to start" - that's the Enter key. Also, if you have a menu up with the Tab key, you need the Enter key to get to sub-menus, or exit it.
Tilde - MAME OSD as I said
Shift - Nothing other than default P1B4. The previous post about shifted keys was referring to how you can press one button and then a second button on the encoder and have it send a different code.

Thanks Tiger that's very helpful.
Unfortunately I only have a 3 button cab so I can't use option 4. I don't like shift functions either. I think the best solution will be to just wire in a second coin button.
I had another though regarding the PC power button- I've seen push buttons that light up somewhere, which would be great for a PC power button (assuming the lamp is compatible).

That's what I decided also. The only other thing I could suggest at this point is to see which dedicated coin games you want to play and see if one of the other workarounds would work for these games.

Sounds like a good idea, but I don't know what the lamp would need to use for it to work, maybe someone else will. (might want to start a new thread on Lamps for PC LED's).

Does anyone have an image and/or step-by-step on how to attach an external button to the power button on the pc?
More specifically if possible, a standard ultimarc switch button similar to"Player 1 Start" button attached to the computers power button.
