TODO:

- Background is misplaced in wbmlju

- Sprites stick in Pitfall II

- Sprite priorities are probably wrong

- Remove patch in noboranb if possible and fully understand the ports involved in the protection


NOTES:

- Up'n Down, Mister Viking, Flicky, SWAT, Water Match and Bull Fight are known to run on IDENTICAL hardware (they were sold by Bally-Midway as ROM swaps).

- MAME skip the long IC CHECK in Teddyboy Blues and Choplifter, this is not a ROM patch, the game checks a RAM location before doing the test.


Inp:

- flicky, seganinj, 4dwarrio, possibly others: Require a steady frameskip of 0 to playback correctly. Will lose sync if the frameskip starts to change. inp061ora
