information 0.28 [Christopher Kirmse, Aaron Giles, Brad Oliver, John Butler]


WIP:

- 0.122u6: Aaron Giles added clocks to the MCR sound boards and some of the MCR games. Added TMS5220 variants TMS5200 and TMC0285 as proper chips. Changed MCR Squawk & Talk sound board to use the TMS5200 as documented.

- 0.117u2: Ernesto Corvi fixed incorrect implementation of SSIO volume controls in the MCR driver. This makes the engine sound in Spy Hunter audible again, among other things.

- 0.115u4: Aaron Giles added support for scaling graphics layouts automatically. The X and Y scale factors are specified in the gfx_decodeinfo structures. Updated the MCR driver to use this feature.

- 0.100u4: Aaron Giles marked all the games in mcr.c with GAME_SUPPORTS_SAVE.

- 0.99u1: Aaron Giles undid a hack that was accidentally left in the MCR games in the last release. Changed visible area back to 480x512 and VSync to 30Hz.

- 0.99: Changed visible area to 240x512 and VSync to 60Hz.

- 0.98u4: Merged mcr1.c and mcr2.c to mcr.c driver. Aaron Giles consolidated the MCR 1/2/3 drivers and documented all the PCBs.

- 0.98u2: Added vidhrdwmcr.c. Removed vidhrdwmcr12.c and machinemcr.h. Aaron Giles partial rewrote the MCR video system. Should still work roughly the same, just a little different under the covers. This is still very much a work in progress.

- 0.98u1: Aaron Giles did some major cleanup on the MCR drivers: Implemented Super Sound I/O interrupts properly, filled out all memory maps according to schematics, fixed sound sync with various sound boards, allowing for kludges to be removed from Power Drive and Star Guards, re-verified all connections from wiring diagrams and documented various lamp and driver boards from the games.

- 0.60: Added prom ($0 - from shollow) to all games.

- 0.58: Added includesmcr.h.

- 18th November 2000: Aaron Giles updated the MCR drivers' video routines to use pixel plotting functions instead of direct bitmap drawing.

- 19th October 2000: Craig Aker submitted an MCR2 driver update with support for Two Tigers dedicated romset.

- 0.37b2: Merged vidhrdwmcr1.c and vidhrdwmcr2.c to vidhrdwmcr12.c.

- 0.37b2: Aaron Giles accurate the sprite drawing in MCR1/2 games. Fixed gfx2 rom loading.

- 0.37b1: Aaron Giles fixed sprite colors in the MCR2 games, however overlapping sprites are still wrong.

- 0.36RC2: Aaron Giles fixed volume control in the MCR games.

- 0.36b6: Added machinemcr.h and sndhrdwmcr.c/h.

- 0.31: Removed sndhrdwmcr.c.

- 0.28: Added mcr1.c and mcr2.c driver, machinemcr.c, vidhrdwmcr1.c, vidhrdwmcr2.c and sndhrdwmcr.c. Christopher Kirmse, Aaron Giles and Brad Oliver provided a MCR I/II/III driver, supporting: Kick, Solar Fox, Tron, Two Tigers, Domino Man, Satan's Hollow, Wacko, Kozmik Kroozr, Journey, Tapper, Discs of Tron, Demolition Derby, Timber, Spy Hunter and Rampage.

 Bugs
 ----
 One of the ROMs appears to be corrupt.  Sark has a few different standing 
 positions sprites. A few of them are corrupt, or the program is pointing 
 to the wrong ones, because at least two of the positions are replaced 
 with nothing, and a red disk, so it appears as if Sark disappears from 
 time to time.  I'm sure a clever person with a MAME debugger could figure 
 out the problem and straighten the sprite issue out.  Otherwise, the game 
 appears to play fine.  I am attempting to find someone with a version of
 these EPROMs and see if I can get a non-corrupted version.  
 
 
 How to quickly tell which version you have
 ------------------------------------------
 During the points/scoring screen, if the bottom item is
 "Derezz a ring    2000", then you have this version.
 
 Differences between version 1 and version 2
 -------------------------------------------
 Most obvious differences are in the test menus.
 
 Sounds menu: there is no test for 5) Tilt, 7) Ring up, 8) Tron up.  These 
 sounds are still present in the game, however.
 
 Inputs menu: this version simply says "Activate all devices.  Tilt to exit"
 whereas the other versions says it a little better: "Activate all player
 input switches and devices.  Hit tilt to exit"
 
 In MAME, the boot up appears differently.
 
 During the demo, when point values are displayed, there is an additional
 "Derezz a ring 2000" that is displayed.
 
 Speculation
 -----------
 The additional "clean" text and additional tests leads me to believe this
 is an earlier version of the ROMs.  However, the additional the of the 
 "Derezz a ring", and the fact that the other sound rom dates differ from
 the sound rom dates that match the other version, might contradict this.
 I would need to see the actual dates on the other versions ROMs to make
 this decision.

 A7-A10 are for the sound board and are 2532 eproms.
 
 CP2-CP9 are for the video generator board and are 2764 eproms.All numbers are
 off by one,so CP9 is actually CP10 etc.etc.
 
 5F,6F,1C-4C are for the CPU board and are 2764 eproms.
