Need to rewrite the ps1 lua metaprogram sometime soonish. Getting too bloated... need to consolidate code paths. In this push codebase structure is starting to get a bit more realized. Decided todo now to match Pikuma's linking module files vods beginning to reorganize its codebase as well. Atoms & atom components are not in their on *.atom.c files. (Not calling it tape.c as I don't really bake tapes like that outside of the unity c file so far...) The lua metaprogram has had additional features added to it yet again to avoid hardcoding module handling and supporting multiple atom files per-module. Either after the camera or cd-rom section I'll be most likely pausing to fully refactor the metaprogram. Possibly as a full re-write to get the loc minimal.
