So the enable line is held low, and you switch controllers as the select line ticks, resetting as enable goes high? Similar to how the 6-button pad sends DPAD all pressed and III IV V VI every other enable pulse?

Console Repair/Mod Center / MultiTap/TurboTap protocol and/or schematic
08/05/2017, 12:44 PM
Hi, lurker posting for the first time
I currently have a project making myself some wireless controllers for various retro consoles (yes, yet another one of those). Thus far I've gotten a PoC SNES sender (I just use the extant shift register in the controller, so it would be possible to just make a plug-in box to make un-modified controllers "wireless") and receiver working. In addition I intend to use a unified over-the-air protocol making controllers interchangeable between different consoles.
I'm currently looking to implement the receiver side for PCE, and as I would like the ability to support several controllers to one receiver at once (the nRF24L01 I am using natively supports 5 RX pipes, how convenient!), it would be nice to implement a native multitap in firmware at the receiver end. This way I do not need to have 5 plugs coming out of a box into a multitap into the PCE. I am trying to implement as much as possible in firmware, to keep the count of external components low.
However, while I have been able to find documentation and schematics on the PCE pads (including ones with turbo functionality and the 6-button pad) I have found none on the multitap.
If anybody has any clues it would be helpful. Right now my only idea is to hook up a logic analyzer to the multitap and observe it in action.
