I thought about heat shrink but decided against it incase I needed to cut a wire or anything.I constantly change stuff around on my superguns.Yea I also thought of running the jamma harness out of the av port,but where the av port is located is where my power supply is,so no room there other then the audio and video outs that are there already as is.Yes the power supply supports + and -5 and +12 volts.No problems there.However the jamma harness didnt have the wire soldered on,yet another reason why I didnt heat shrink the wiring yet,and honestly I dont care to mess with Midway games.They have too much mess going everywhere.Are there any other games that require -5 other then US crap from Atari and Midway? Im not exactly a big Narc or MK fan.
All in all I fit alot of stuff in that Master System shell,and it was not easy.They are not very spacy.There are things I prob could have done better,but all in all I made it very flexable to be improved by someone else if they desire to do so.As it is Im fine with it.Other ones I have built are a Pelican Arcade stick supergun that has everything including harness running out of it.Those sticks are nice and spacy inside.The other one I did was a white Pc Engine supergun.I posted pics of both of those on pcenginefx.
After seeing some of the crapguns on ebay,like the one with composite only and snes pads for controllers,I felt pretty good about this one.Its well rounded.
