Ta very much everyone for your great comments!
I just have to do something about the backglass, it looks ok unlit but has quite a few cracks in the ink. Some of it will touch up fine i think, but a lot of the damage is in the lit areas unfortunately. I might post some pics later on of the game before and after and maybe a few detail shots if anyone would like to see more. Also if i can make the backglass look "decent", i'll post some details and pics here at a later date.
As for the board test rig i'll have to sit down and draw out the schematics. I used mostly stuff i had in hand, the only thing i bought was the LEDs, and made my own circuit boards. I might even do a thread later on detailing what went into building it! its kind of a work in progress as i still want to add more functions onto it as i need them.
