I'm building some JAMMA adapters for various boards I have to test, and I have a question for those who do the same.
When building an adapter for a game that has other games that can be swapped in, how do you decide to build it? For the game that has the most control inputs? Or just the basic power, video, sound, and generic controls so you can tell if it's working?
The reason I ask is because I plan to build one of the Taito Classic ones to test some boards (I know all Taito Classis's aren't the same, but the ones i have all have the same power, video, and speaker setups), but some boards only have two buttons, while others have more complicated control panels. Do I build it for the most complicated? or just get it where I can start and make sure I have good gameplay and not worry about whether a fifth button works, especially if buttons 1-4 do.
And I'm making a JAMMA-to-Sega System 8 so I can test a couple Choplifter pcbs. Should I just build it for the Choplifter, then add some extra jumpers later if I ever have a different System 8 board that needs more? or do I look up the pinouts on all the System 8 boards, and build the adapter to fit that one, knowing all the others will work with it, too?
Also, does it matter which buttons I wire up as S1 and S2? For example, a Scramble psb has inputs for Fire and Bomb. As long as can tell they are working, should it matter? or should I check the control panel layout and pick the closest to the joystick as S1 and so on?
Opinions? Just trying to make things easier to test on the bench...
