I am quite new to speedrunning and I was hoping to attempt Any% NSC on the latest version of Gambatte. For some reason, after following all the inputs for the manip I can't get it to work. I'm not sure what the problem is... could it be something with the ROM? If there is a specific ROM recommended for Pokemon Blue or something I may be doing wrong with the manip, I would appreciate some advice!

It's not the ROM, it's probably the timing of ur inputs.

Manipulations are much stricter to execute than you may originally anticipate. It's impossible to say what you're doing wrong without seeing a video of yourself performing the manips, but the exact manner in which you see a manipulation performed in a demo video is the precise method that you HAVE to use in order to nail it. There's no such thing as being "close enough" with executing manips.

The only thing that can be happening outside of player error is an IGT0 failure, but I know nothing about Any% NSC manips so I can't say for certain if those can occur.

Awesome! I'll try to work on that and see what I can do to make it better. Thanks!
