I'm pretty sure four pots covers any game I can think of, most don't use more than three and a lot use only two so I'd say that four would be great. Four analog inputs, two light gun inputs, and compliment of standard joy and button inputs would be a impressive feat I'd think. Maybe throw in a rotary support and call it a day?
What would be a "compliment of standard joy and button inputs"? JAMMA+ or what?
Games that use 2 trackballs: Atari Football, Track & Field, Cabal, Marble Madness.
Looks like SegaSonic the Hedgehog, and Rampart uses 3 trackballs.
As pins is almost for free, I could add some just some on the board for completeness...
3x trackballs (6 encoders),
2x extra joysticks for Gauntlet and others,
2x light gun inputs,
8x analog input channels.
+ some extra spare I/O..
...I think that this will fit in a 20x2 standard header on the board.
1x JAMMA+ connector with stereo sound, and extra buttons.
1x VGA connector with separate graphics output, not the same signals as those on the JAMMA connector.
1x 3.5mm stereo audiojack or 2x RCA for sound (not decided yet).
1x SD card slot for your ROM copies,
1x USB for upgrading.
1x More on board RAM memory, than needed to play all NEO GEO games.
Thats about it.
No harddisk,
No fans,
No moving parts,
No PC,
No software emulation,
No operating system,
No lag,
Just Real Hardware...
All we need is love

Anyone interested?

I think thats about it. I think I could get it ready october-november, if some one want to beta test.
In October we will see how many games i have managed to support. But It will be total mayhem in the beginning and it could be good with some beta testers with balls of steel, there will be hundreds of games to test. I will be doing much of the initial testing on another platform starting in about 4 weeks, but will try to get this dedicated JAMMA platform as fast as possible. And I will have one month of research until then... No rocket science, but it will be a small steep for man but a big steep for gaming

I have to get some girls giviŽn me some sweet lovin to manage this

Well this is the new dawn of hardware, I think we are somewhere around 1998 in MAME time at the moment. And we have some catching up to do...
And I think 1998, 1999 might be some fine years before the new Melania.
And I have reserved 100% of my time one year from now to hardware. I'm going to study asic design and custom computers fore one year. I think they made a c64 in a joystick, and now I want to make an entire arcade hall in a game pad
