77TODO:
88- YongYong mapper:
99  - During start there are 2 writes to 5000 and 5003, it is still unknown what these do.
10- Story of La Sa Ma mapper:
11  - Does this display Nintendo or Gowin logo on boot?
12  - No clue how the banking works yet
13- ATV Racing/Rocket Games mapper:
14  - How did this overlay the official Nintendo logo at BIOS check time? (Some Sachen titles use a similar trick)
