OKAY SO there you go.  I believe that's pretty much everything.  I could have modified the source after I compiled the ROM, to test other junks, but I believe I fixed it back to how it should go.  I created the tiles there for this ROM too, so I figured I'd include those files as well, in case you actually did want to compile it.

Also, this was done with the GameBoy Developers Kit, which may have been updated since I last downloaded it.  But I recommend it to anyone wanting to develop ROMS for the GB and GBC.
