I wonder if I would be allowed to use another simulator. Like BizHawk Nestopia Mesen. Do not include VirtuaNes. Thanks

                  -I'm sorry that my English is poor so I used the translation software

According to the game's speedrun rules, the only emulator that isn't allowed is "Gotvg" I suppose that everything else should be fine

OK thank you

Yeah, Gotvg is not allowed. Everything else, for now, is.

I personally suggest everyone uses Mesen v0.9.7 or higher.

thank you

How do I disable Left+Right in mesen.

You need to go to Options> Emulation > Advanced and then uncheck the "Allow invalid options" checkbox

What should I do

...You just disabled it lol This is fine as is :P
