@bio_hazard1282 The PS5 controller has a touchpad right? If so you should be able to use that to emulate the stylus.

I wonder how quickness determines the region - there's nothing in the Core Options (like Nestopia or Fceumm) which can select the Region. How is the ROM file named ?

@thelostsoul The game is still available on the original release forum topic.

Here are some tips for reducing input lag. You'll never get an emulation setup to completely match actual hardware, but you can improve things greatly. I just beat 'Super Mario Brothers 3' a few weeks ago and almost got a TKO on Tyson earlier today.

@mediamogul Yeah, I have to wonder if something in a kernel update caused things to get funky.

For what it's worth, while adding this week's MAME ROW games to my system I updated to 4.3.15 (07d9f95) and it didn't resolve the issue. I'm hoping either reverting to a really old version of RetroPie and then just not doing any updates, ever, or updating to the new Stretch version will resolve the problem. I haven't made the time yet to disassemble everything and put a different card in to try that route.
