Noxid is talking about adding more songs by putting their names into ASM somehow, and that there's only room for two or three more songs, unless you do some optimization or put them somewhere else. Wedge wants to create a new TSC command with the TSC parser, and I think it was Lace that was talking about the TSC parser, which you can use to change or add TSC commands, as well as their names.
