Mysterious Stones - Dr. John's Adventure

0.66 [David Haywood]

0.25 [Nicola Salmoria]


WIP:

- 0.113u2: Changed VSync to 57.444853 Hz.

- 0.105u3: Added 6x 'Unused' dipswitches.

- 21st April 2006: David Haywood - Mysterious Stones has been broken since around MAME 0.77u2. There are a few bad tiles near the start of the first levels, and by the 2nd level it's apparently unplayable. I took a quick glance at the vidhrdw/mystston.c file, the mystston_videoram2_w handler is broken. As an optimization the code is meant to check if the contents of videoram is the same as the value being written to it, and then only write it if it isn't the same. The mystston_videoram2_w handler is checking the wrong video ram. Fixing the bug was a_very_ simple one line fix.

- 0.77u2: Curt Coder improved Mysterious Stone driver based on schematics. Changed VSync to 57.444855Hz. Added 'Flip Screen' dipswitch and removed all unknown dipswitches.

- 25th November 2003: Curt Coder added correct video timings to the Mysterious Stones driver.

- 0.66: Added Mysterious Stones (set 1).

- 6th January 2002: David Haywood added a newer version ROM set to the Mysterious Stones driver.

- 24th August 2000: Zsolt Vasvari converted Exed Exes and Mysterious Stones to the tilemap system.

- 0.36b4: Changed palettesize to 56 colors, added color prom ($0) and 'Demo Sounds' dipswitch.

- 22nd August 1999: Zsolt Vasvari fixed Mysterious Stones colors (that's the game which has been broken for the longest time).

- 0.34b3: Nicola Salmoria added sound in Mysterious Stones. Added 2x AY-8910 sound.

- 0.28: Mike Balfour added hiscore save in Mysterious Stones.

- 0.27: InputPorts now can automatically handle VBlank bits. No more need to write custom code. Mysterious Stones use this feature.
