Pushing B doesn't do anything in the race. I'm 100% sure that it does nothing. If you want to go slower, you simply press A less fast for a little bit. I know of this strategy I've read it all over the internet. The point is, I don't want to have to destroy my keyboard to win the stupid race twice. I just want to hold down a turbo button. I've read that turbo buttons work on the N64 to beat the race.
Are there are plugins with a turbo fire that works? I mean, its been what, almost 10 years since the N64 came out, and there has to be a viable method to use turbo mode on an emulator to get this to work.
