Cannot speed up games #1087

Closed electraminer closed 6 years ago

electraminer commented 6 years ago

I have been trying to speed up my game (SMB1) to go faster than 100% speed, but the emulator will not go above 60fps. I've tried everything I know of - unthrottled, turbo, and normal speed change. Everything just sets the speed at 100% or 60 frames per second. I can use these speed features to slow down the game. Is there a setting somewhere for frame limiting?

NESHawk is slow. It's possible it's already goiing as fast as it can go.

The other core in BizHawk is QuickNES.

Load the game, and then in the menues go to NES -> Core -> QuickNES

Then in the menues go to Emulation -> Reboot Core

It should now say 'QuickNES' at the bottom of the BizHawk winbdow.

Try changing the speed now.

I can't find any actual bug here, so closing. Feel free to reopen if you are having trouble even with QuickNES

When I open the emulator, it says "Unable to open QuickNes, using NesHawk instead".

That means your game is unsupported by QuickNES (it has limited mapper support and is a bit glitchy.)

Looks like you are basically stuck at 60 fps.

Another fast core is gambatte, maybe try some GameBoy games and see how fast you can get them to run? It should be a few thousand fps.

EDIT: Originally you posted that SMB1 was the game you were playing, this definitely works on QuickNES, are you sure it's a good ROM? What version and OS are you using?
