0.16 [Marc Lafontaine]


NOTES:

- venture, mtrap: Coin 1 and 2 are listed twice in the key mapping. When the "coin" buttons are pressed, 2 addresses are checked (look at the info in the source file), and the only way to handle this is to have the keys mapped twice...stephh


VIDEO HARDWARE NOTES:

- Exidy hardware checks for two types of collisions based on the video signals. If the Motion Object 1 and Motion Object 2 signals are on at the same time, an M1M2 collision bit gets set. If the Motion Object 1 and Background Character signals are on at the same time, an M1CHAR collision bit gets set. So effectively, there's a pixel-by-pixel collision check comparing Motion Object 1 (the player) to the background and to the other Motion Object (typically a bad guy).


Inp:

- mtrap: Playback doesn't work correctly unless sound is disabled when you record them. inp061ora
