I’d like to help out in debugging the controller issues.
Tonight I noticed that it happened while playing in the mednafen_fce_fast core. From what I can tell, it feels like the input “locks” for a very small period of time, and then I regain control. It’s definitely less than 1/2 a second. Happened 2 times that I could be sure of, in about 20-30 minutes of play. I’ve also encountered it while using the snes9x core, and feels like the exact same issue.
I pretty much always play using a Classic Controller, so tonight I tried playing with just a Wii-mote, on the same pce game I had been playing before. Played for about the same amount of time, and didn’t notice any issues. Though, playing with the wii-mote d-pad causes lots of issues on it’s own, so maybe it was hard to tell. It would be nice to hear from others who have this issue, and what kind of controller they are primarily using.
I also had a thought, since it seems to happen very rarely (and maybe only with a classic controller?), could it have something to do with the Wii-motes trying to go to sleep after a timeout?
