NES SNAC unable to detect controller, SNES core SNAC is able to detect controller about nes_mister HOT 2 CLOSED

the implementation of SNAC in NES and SNES cores are effectively identical. The cores themselves and how they read controllers are radically different of course (following the extreme difference of the hardware itself), and there's no chance the logic of reading controllers will ever be changed in the NES core.

If you have an OEM NES peripheral that is not working correctly, then the implementation of the voltage level converter is likely to blame. The protocol (Latch, clk, data) is ultra-simple for nes/snes and I see nothing that really could be changed to change t he outcome regardless.

Figured that was the case. I have an old SNAC adapter that works fine - just was confused when I saw the NES controller light up in the SNES core - figured I'd raise it up just in case.

Whats odd is that it /did/ work at one point so wasnt sure if something changed - couldnt tell you how long ago that was though.
