Trainer/fly in Mt Moon?

[wwwxxyy]

I was reading this post and the dude mentions it. However, I can't make it happen. As far as I can tell, the only trainer you can warp away from is the Rocket Grunt guarding TM01. But whenever I re-enter that floor, with my menus back, I don't get any start menu or dialogue box, and all the trainers ignore me despite having the menu back.

Am I overlooking something?

It was in a TAS used to get a Gyarados, you shuold be able to find it on tasvideos.org

Well, after dicking around with this for a retrospectively frustrating amount of time, I'm confident that for whatever reason t/f on the TM01 rocket doesn't work after you've already been through Mt Moon, something I wish had been mentioned somewhere...

Yeah, probably you need to fix the Start menu outside Mt. Moon and later enter there again, or caves simply don't work. I never did it before. ._.
