I saw the words "CHARACTER EDITOR" in the ROM after curiously looking through it, so I did a little tweaking and discovered a way to hack the game to access it. This PAR code with enable it from anywhere in the game: 004C0A:4E71 Now to get to it, hold buttons B and C, and press A. You'll see a bunch of crap appear on the screen and the words "CHARACTER EDITOR 3.52" under everything. The character editor allows you to modify the VRAM. You can redraw individual sprites, and you can change the color palettes too. Press start to restart the game and ignore the changes, or hold B and press start to save the changes and proceed. Nothing too major, but I thought it was an interesting find.
