Need help on an auction purchase!

[OldSchool33]

I recently purchased this arcade system at an estate auction.  It work (turns on, boots up), but the joystick controls do not work.  I opened the controls up and I noticed that one of the wires is burned, coming off the computer (Blue Elf 2008 v 1.0) to the controls.

Should I replace the Blue Elf unit with a more up-to-date system or just replace the wire harness?  What is the best solution?

Any help is appreciated,

I am not familiar with a Blue Elf, But a burned wire is obviously a bad thing, I would seriously  map out those controls just to be sure they are correct, but thinking you got a amperage problem, and personally would replace that with a switcher.
