Alright. And when I get back on my PC, I have a video to show you.
It has:
-A 12:29 song
-That song sseq being about 80 000 bytes
-That song playing and not killing the emulator
As well, I got my hands on a NO$GBA debugger version. We can look at 3D attributes and see seperate entities and where they're drawn on the screen. Fast fact: In DP, there is a texture written to the RAM that says "MART" but is not used because marts are depicted by blue roofs.
