You're right Pete, this one's pretty intense for a kid's coloring game.
It basically boils down to sync length counting.
1. Track 36 has to be no-sync.
2. For track 37 it looks for a certain sequence of sync marks that have specific lengths and then retrieves 2 bytes following 2 other specific sync marks.
3. For track 38 it looks for a specific length sync mark followed by a $72 byte, skips the next sync mark and byte following it, then skips $800 bytes and reads in 15 bytes.
The flurry of head movement after this is just to freak you out, it doesn't actually do anything.
Some text in protection:
-(C)85-SILICON DRAGON SOFTWARE & STEPHEN MEIROWSKY-WICHITA,KANSAS-03/14/85-SOFTWARE PIRATES DIE!:WEAR THE ALBATROSS!-SUSAN,I LOVE YOU!
If you give the protection what it's looking for, the game works properly. This protection is also reproducible, the image just needs to have the sync lengths modified on tracks 37/38 to match what the protection is looking for. This should then remaster properly as well.
Once again, all this effort put into a protection scheme and they don't even give you a fast loader. Bums.
