@suloku I know that not much is happening in the thread, and the project is pretty much over, but I'm hoping to get some help. I really want to inject a custom Altering Cave Wondercard into Emerald and Leafgreen. I saw earlier in the thread something about injecting a script, but I don't know how to make one, and can't find one that's already been made. I saw that there were plans to try to make a Wondercard for it at some point, but not really sure what's up with that. Is there any way to make this work? Thanks!
