Hey everyone- I’ve been doing lots of work on roundabout wireless controllers, and just now I got my VB to SNES one working! This one is kind of a hackjob since it’s my first for these systems, it’s easier to just throw it all together and see what happens since I always have to solder and desolder a bunch of things to fix bugs anyway 🙂

My stupid iPad took a nice blurry picture but I’ll try to update this once I’m back home in the morning. Upon initial testing, pretty much all the buttons work fine except up/down on the left Dpad seem to be shorted. Pushing up makes Mario duck in Mario World, yet I can still navigate fine on the map (and throw shells up in the air even though he’s ducking).

This project is fairly simple (and cheap!) just tasky…I hacked up a $20 RetroBit wireless pad (the black one) and just linked all the SNES button traces, grounds, etc to those on the VB. The chip in the VB was removed. I thought I had bricked the thing when trimming away the RetroBit circuitboard because it wouldn’t power on, but all I needed was to link one isolated area back to ground.

this looks awesome !!!!
one question.
what do you connect to the SNES in order for it to recognize the thing?

Thank you! Well the RetroBit controller comes with its own little receiver. I can just leave that as-is, but I think it would fit in a VB game cart…that would look cool plugged into an SNES. This is for a custom SNES mini for a friend, so the receivers may end up hardwired into the system.

Does the transmitter support A and B, are they just left disconnected, or did you hook them in parallel with other buttons?

I’m also curious about what you’re going to do with the 10mm LED…

I think I wired A and B up to B and Y. I haven’t played much SNES lately but that seems like a good combination for games that may have a jump/attack setup on B and Y. If I get ambitious I may work in some jumpers to reassign those buttons on the fly externally.

The 10mm LED will be aimed straight at the gamer’s eye to simulate a Virtual Boy session :). I was actually messing around with trimming more PCB and wanted a really obvious indicator of a sudden loss of connection to the battery.
