================================

Some enemy ROM information that I'll add just in case it's useful to someone:

The largest enemy plane you encounter part way through the 1st level has it's HP values stored at ROM addresses 0x11F50 to 0x11F55.  There are 3 different 2 byte values (300 HP, 350 HP, and 500 HP).  Pretty sure these relate to the 3 different difficulty levels in the option menu (Easy, Normal, Hard).

The next large enemy HP values are @ 0x011F8A, then 0x3A bytes after that, etc.
