The rom runs in desmume and no$gba emulators. The game mechanics seem broke. You can walk into black empty areas which typically doesn't happen with most games that block you off with invisible walls.
I did more digging into this rom with DS Buff rom extractor. Yah, this rom is setup wrong compared to typical NDS/DSi roms.
I think I found the issue that's making it fail to run. There's some missing extended header info and 00 padding. I believe the rom is correctable.
Well, that answers my question. Thanks!
Sadly its not complete and there's not much that can be done about it. U_U
