OpenSFC Controllers

These controllers replicate the major design iterations of the SFC / SNES Controllers. There are two models produced: 1990 Model: Original launch model that uses two 8-bit shift registers. Note that this model is not PAL compatible without modification 1992 Model: Revised version that uses a single 16-bit shift registers. If the Only-P resistors are placed, it can also run on PAL systems. DISCLAIMER / COMPATIBILITY NOTES: Building a controller with third party parts almost always requires tuning for micro-tolerance issues. All parts (boards, shells, rubber pads, buttons, etc) have tolerance ranges that may not overlap cleanly in all combinations. Even a small 0.1mm gap resulting from tolerance clashes between parts can reduce sensitivity, specifically on diagonals on the d-pads or the shoulder buttons. Please note, these issues happen on the stock boards too, this is why 3rd party silicone pads are notorious for stiff diagonals. As these boards are 1:1 replicas of stock, the same thing
