Is it possible to configure a key to switch between keyboard and controller in a run to be able to do BLJs with keyboard?

You can do it pretty easily, but it won't be legal to submit to leaderboard. Keyboard is a digital input, so you'd run a foul of the controller restrictions at the bottom of the rules section if you switched mid-run.

I'll note that keyboard + controller IS legal for Emulator runs, and I think you can just have them both enabled at the same time. Probably doable with like the wermi fork of octomino plugin.

Thanks for both answers. I’ve read the rules, and It says that scheme must be the same. The restriction is that you can’t map analog to digital and vice versa. As for the plugin, I found it, but it doesn’t allow the keyboard as an input.

That rule is for Console Runs (N64/VC), not Emu... Listen to Twig

True, I didn't realize that. However, I still can't find a way to use both the controller and keyboard in the same run
