How to put a transforming stage (uses STGEMBLEM files) in a custom stage slot?

[cucco002]

Hello everyone!

I use the stage expansion code and I wanted to add this stage to my game, but I don't want to replace Castle Siege. The stage provides files that I can use over others stages, but I want the transforming version, and for that only Castle Siege would work (I think).

I want to put this stage in a custom stage slot, the problem is that it uses many files (STGEMBLEM.pac, STGEMBLEM_00.pac, STGEMBLEM_01.pac and STGEMBLEM_02.pac). This wont be a problem if I were to replace Castle Siege, but over a custom stage I haven't been able to get it to work in the past.

Anyone knows how can I do it?

If anyone is interested, there is a tool created by Mewtwo2000 that lets you to alternate between stages that use the same .rel file just like Mushroomy Kingdom has 2 alternate versions, I could do that, I guess, but I would like to use a custom stage slot instead.

Thanks for your help!
