Hi, I'd like to run BizHawk at a speed greater than 400%. Is there some source code line or whatnot that I could edit to change 400 to, say, 2000? I naively edited the config.ini file but that didn't have an effect. Thanks

Is your computer capable of it? Which systems did you try it on?

I am running BizHawk on a laptop with a 8G RAM, an i7 broadwell CPU, and a GTX 800 M series graphics card. When I run the emulator at 400%, it shows no signs of struggling.

use shift+tab to run unthrottled or set SpeedPercentAlternate in the ini file

Thanks for the info. I'll give it a shot next time I have the chance. I have another related question regarting unthrottling and speedup: A lua script plays the game in my case, and so does not rely on graphics rendering. It simply collects statistics. The documentations says "Make sure you're not using GDI+ display method. It's slower by far than OpenGL or Direct3d, which is preferable and should be best for most cases." Is it possible to switch off rendering completely? [edit] - Might have answered my own question. Threads like this one suggest it's not possible. https://code.google.com/p/bizhawk/issues/detail?id=267 What I was suggesting is apparently known as frame skipping and has issues.

config > display > misc > absolute zero. frame skipping doesnt have "issues" if your goal is to see absolutely nothing at all but absolute zero was meant for people who dont want to see anything.

Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

400%? The emu lets you speed it up to 6400% by using the Decrease/Increase keys (configurable in the hotkeys menu).

he wants to bind a faster speed to the fast forward key
