 * Free Movement Mode - Unclear how this would be accessed, but would allow you to use the D-Pad to move around the level (see disassembly source for PRG bank #0, search for "$C3EA").
 * Toggled Invincibility - Pressing Select would toggle whether you were completely invulnerable (see disassembly source for PRG bank #0, search for "$C91B"; this behavior could be easily restored by retargeting the instruction or moving the Objects_HandleScrollAndUpdate label since this method would fall through into normal game code).
