Hi hizoka10,
Yeah I found out about only needing the _rgb a few days ago. I didn't update the zips in this thread because I intend on only doing weekly updates. Thanks, though.
You're free to upgrade SM64 textures, but I think I'd rather continue up till the end for my pack (except maybe the text or character textures). I want to stick to a certain "painted" and slightly grainy style. Your textures don't really fit with that.
Little word of advice, some textures don't need upgrading at all. I noticed you upgraded the butterfly and star (on the doors) textures, but these are so small in-game that it doesn't make a difference IMHO. Also, you might want to add a little detail to blown up textures, like brush strokes, lines, and slight grain. A lot of your textures are nice, but (i hate to say it) some others look like they were only scaled up with bicubic filtering, maybe a bit of median (like the metal rusty door for example). In my opinion, it's only worth upgrading textures is actual detail is added, much like your pretty green marble-like texture, turquoize glowing pebbles, and others.
