So some backstory: I've been having a good time playing Pokemon Gold on VC, but after raising a Growlithe the whole game, I only recently realized that you need to beat the Johto E4 and make it to Kanto before you can get a Fire Stone!! I didn't want to wait that long, so I decided I would make it to Celadon in my Pokemon Blue game, buy the Fire Stone, trade the Growlithe over, evolve it, and trade it back. Very convoluted, but it would work. Instead of playing through the game like a normal person I decided to utilize Brock Through Walls to make it to Celadon. Fire Stones are quite cheap so I figured I could just go over there, buy a Fire Stone, and be done with it in under half an hour.
It took a lot of tries, but I finally managed to get a Level 8 Bulbasaur with 16 Spc and a Level 4 Pidgey with 15/18 HP. The Bulbasaur has 26/27 HP, and its PP is all over the place, but I figured the Bulbasaur + Pidgey would be enough and I didn't need to worry about PP. Good news: The glitch technically works. I can move wherever I want.
Bad news: For some reason, the menu will not stop popping up if I stop moving for even a moment. Even worse, every step downwards is a battle; the game often just endlessly opens up my menu, or forces me in some other direction. I can move upwards or to the right just fine, but the game seems to hate moving the player down. I've tried canceling the menus, but they're endless. I've tried sitting back and seeing where the game will take me, but that ends up crashing the game or ending the glitch. Through a lot of finagling I can make it to Cerulean City, but sometimes the glitch just ends there for what seems like no reason; I haven't entered any doors or anything. As such, I can't walk over the Saffron gate and over to Celadon. This is especially frustrating because I don't know the path to Celadon by heart, so needing to be constantly moving in an upwards or right direction when there's doors and out-of-bounds areas everywhere can get annoying.
Does anyone know what's happening that makes the glitch so frustrating to work with? Is it because my Pidgey has a total HP of 18? I'd really like to figure this out because I already wasted 2 hours just trying to evolve my Growlithe that isn't even in this game :(
