Well so i just recently got a new keyboard and instantly plugged it in because my old one broke and then i realized in games like minecraft it stopped walking for some frames then it started walking again and it was like the keyboard had input block spikes, i could easily fix it by plugging the keyboard in and out and now it seems to work in any game except in snes9x because i still get very laggy/choppy weird input which is super annoying especially at smw kaizo hacks

Thanks in advance ^^
