(6) To enter test mode press 9 (open door), then F2 (turn function key), then E (bet 3-4).
(7) Bad tilemaps colors in demo mode are real game bug. Fade-in and fade-out "bad" colors are also right.
Bad sprites priorities are real game bugs.
Bad sprites priorities are real game bugs. The bad-looking colors in Jurane stage are right.
Notes:
- The NEC D4701 used by Caliber 50 is a mouse interface IC (uPD4701c).
