I've been thinking more about the design of my own SuperGun which I plan to make, mostly because I've found a cheap Naomi which I plan to get to start my little collection. It comes with nothing but the bare system, but I don't care, I would just love to see the Naomi logo bouncing on my screen

Anyway, I need some help and some varifications on a few things, and advice would be nice.

Fist of all is my control method. I wasn't sure how I'd do this, but after connecting my MegaDrive pad to the parallel port on my PC, it ocurred to me "Why not use this?". They're pretty much perfect for using, since they come in both 3+1 and 6+2 varients, which is perfect for the vast majority of games, and reading the inputs is simple. After a few tests to learn about the interface, I learned that all the multiplxer is is just some transistors in a DIP package. However, to use them on a Jamma interface, I figured I'd have to use a small microcontroller like a PICAXE to read the controller and convert the outputs into steady forms. The idea for 3-button controllers was to select a state for the signal, read which buttons were pressed and store them, activate these pressed buttons to the relevant pins on the Jamma interface and remember these, change the signal state and read any other buttons being pressed, do the same as before, change signal and see if any differences have happened, if not, change nothing and change state. I wouldn't have a clue how to keep this in a certain sync to change without serious delay, nor would I know how to program this in PIC's format. Is this a good program idea? If so, help?

Also, because my SuperGun is going to have proper cabinet features, I was looking at coin meters. Havign a look at some thingd, I figure these a controlled via pulses and it stores the changes in an SRAM whil displaying the current count. That's my theory, but not having a Jamma board, coin meter or even any testing equipment, I couldn't verify this myself. Anyone else know how they work?

And finally, would anyone know wehre to buy cheap connectors for JVS/JAMMA ports? Also looking for Molex connectors too.
