Hey everyone. New to hacking and Been doing pretty well with it and needed a little help. I downloaded 3 of lensho's stages. Cerulean,Saffron, and vermillion gym. I wanted to add each one to Spear pillar seeing as spear pillar has 3 different stages so to speak. Here's the issue though, I'm aware that both Vermillion and Saffron use battlefield as a base but Cerulean doesnt. it uses jungle japes (melee). Cerulean works fine on its own but I would really love for all 3 to be over spear pillar. I made icons and everything

. I've tried using a final destination based rel file and the stages partially loads. Is there any way to change Cerulean gym's base from jungle japes to battlefield with the rest? or is that not possible or is it up to the creator Lensho?
