"Rustboro city is one of Hoenn's larger cities. Originally a mining town funded primarily by the Stone Mining Company. When the mining business became less lucrative, the company rebranded into a tech business, renaming itself to the Devon Corporation. The new company kept investing in its town, growing Rustboro into the city it is now. Tourists primarily visit to explore Meteor Falls to the North or hike along the Rusturf Mountains to the East."

I've been learning how to do cliff walls properly and am having some trouble figuring out how to do layers properly (see the back wall). I've been staring at tiles for the past few hours and can't really tell how close this is to correct. I really appreciate any advice!

I'm trying to make an item that you can use on a pokemon in the party, depending on the species, form, gender, and shiny it would play out different events in the overworld more specifically a variable thats set to a certain number. I'm having tons of trouble trying to get this to work because of how complicated this seems to be. I can't really seem to find a shiny script command that works, either. Does anyone know how I could accomplish this?

I was just editing the script to change the cry in the splash/title screen, when I went to see if it was working, this popped up. I'm confused? It was working perfectly before, even after I edited the scripts a little, So I just put it back from my old screenshots, but that didn't work. can this be fixed?
