Project 64 1.6 is already very old and clunky. Why is something like Mupen in Retroarch not allowed?

Does this mean 2nd Run? Because I dont find anything on ng+ in re2 on google.

When I play celeste on my pc I have a locked 42 fps in fullscreen and i dont know why but in windowed mode 43 fps. I tried vsync and stuff but nothing helps. I also tried vsync in the nvidia settings but doesnt work. I even had this problem on my old laptop where I thought it looked laggy because the laptop wasnt that good but even with my good pc i get 42 fps

Im using bizhawk is it allowed or should I use nestopia or fceux?

Because i dont have a capture card I record with my phone and I dont want you do hear me or my brother

which controller are you using on emulator?

Keyboard sucks and ps4 and xbox controller feel odd. Which controller are you using?

I dont have the money to buy a capture card. Do I need to proof my run?

Can you speedrun with a r4 card or does it effect anything?
