is there a way to extend the level art in sonic 1 github?

here is axel srh and sorry for so many questions but I have had this question for years and is there a way to add more art to the levels of sonic 1 github?

 

Like, add more tiles to a singlular level? Something like SonLVL can easily do that.

 

add new blocks without breaking the level

 

I'm not sure what you mean. You're gonna have to be more specific.

 

when trying to import new art to sonlvl I get this even if I remove the ones that are not used

 

That may be the cause of having more than $52 chunks in SonLVL. If that's not the case or you need additional art room after that you'll have to edit pattern load cues.
