i will take a picture for you and upload tomorrow. essentially i made it in 3 sections, the base, the joystick panel and then the top half with the monitor etc
the base inside i cut a hole at the back and built a subwoofer box inside so the bass booms out of the back. the amp is fitted to the top of the subwoofer.
i had it all running nice on my original bootleg board, i made custom kick harnesses and all of that, recapped the board etc but it developed a sound issue and a graphical glitch that wouldnt go away so at the moment i am running the rom through a raspberry pi. but i am able to run it with a nice crt filter which helps maintain the old style look to it
