As far as I understand it either redefine them or remove them, yeah. Errors like Symbol SS_TalkText isn't in scope
mean that you’re going to want to find everywhere in your files that referes to SS_TalkText
and remove them, yeah.
At a glance it looks like every “Symbol isn’t in scope” error you have can be solved by just deleting anything that refers to those parameters, all of them are tied to skill system stuff. If it feels like you’re deleting a LOT of stuff, that means you’re doing it correctly lol. Just be careful when removing things about brackets, ALIGN 4 declarations, and if statements, as if you remove part of it / the wrong one you’ll likely get crashes or errors when you go to compile.
