I am working on a new version of my Saturn to USB converter (see http://denki.world3.net...) and want to support the analogue controller and multitaps.
The problem is that all the info I have managed to find, such as the official SMPC guide, only tells you how to read the controllers from the Saturn programmer's point of view - they don't actually explain the electronic interface. That's what I need to know, which signal lines do what and what is the protocol used?
Anyone have any information on this? I have taken apart a multitap and it contained a PIC16C84, and I'm guessing that it probably uses some kind of serial protocol. Unfortunately the PIC had it's code protection bit set. |
