0.85u1 [Pierpaolo Prazzoli]


TODO:

- Finish video emulation (colors and flipped tiles?)

- Games known to be needed: Triv Whiz (Edition 3) - (c) Merit 1985 and some other missing categories romsets and new / old revision.


NOTES:

- It's important that REGION_USER1 is 0xa0000 bytes with empty space filled with 0xff, because the built-in roms test checks how many question roms the games has and the type of each one. The type is stored in one byte in an offset which change for every game, using it in a form of protection.


WIP:

- 0.109: More merit improvements [wolf676]: Added external coin counters and coin lockouts. Fixed lamps in upright and cocktail modes. Fixed merge collision from 0.108u5.

- 0.108u5: Some more cleanups to the findout driver [wolf676]: Fixed order of buttons and lamps in the games. Removed impulse(2) from buttons -> buttons respond much better now. Used PORT_INCLUDE() and PORT_MODIFY() where possible. Connected outputs for use with artwork.

- 0.108u4: wolf676 cleaned up dipswitches and documentation in the Merit driver. Added dipswitches like 'Reset High Scores', 'Demo Sounds', 'On 0 Points' and 'Coinage'.
