TODO:
* Add analog sound
WIP:
- 0.146: hap fixed regression in Red Clash driver (hang on boot).
- 0.141u2: Andrew Welburn and The Dumping Union added clone Zero Hour (set 2). Changed parent description to 'Zero Hour (set 1)'. Fixed rom names.
- 3rd February 2011: Smitdogg - Andy Welburn dumped a previously undumped set of Zero Hour.
- 0.135u3: Fabio Priuli added driver data struct and save states to the Red Clash driver.
- 0.131u1: Angelo Salese merged memory maps in the Red Clash driver, also cleaned-up the irq/nmi generation on coin insertion.
- 0.123u2: Changed palettesize to 128 colors.
- 0.122u8: RansAckeR fixed 'Bonus Life' dipswitch.
- 0.111u4: Mike Ellery improved dipswitches in Zero Hour. Added 'Bonus Life' dipswitch. Changed 'Unknown' to 'Unused' dipswitches.
- 11th August 2005: Frank Palazzolo - I bought a Zero Hour board on eBay. Hopefully I can improve the driver when I finally get time to work on MAME again, now that I'm intimately familiar with the starfield generator circuit.
- 0.97u2: Frank Palazzolo cleaned up starfield code and fixed/added starfields to Zero Hour. Changed palettesize to 64 colors.
- 15th June 2005: Frank Palazzolo - I've hooked up the starfield generator code to Zero Hour and Red Clash.
- 3rd May 2005: Frank Palazzolo - Well, I found time to make a few more discoveries. The Space Raider boardset is 3 PCB's. Two of them are full size and obviously two halves of the same design. Then, there is a little PCB grafted on top, connected via a 24-pin dip connector, with wires going to the other two boards. I suspected that this board was the starfield generator. Sure enough, if you unplug it and run the board, the stars disappear. Cool - less work for me. Then, I noticed something else. Two chips were missing from the board, and it was labeled with the number 8011, unlike the other boards. Maybe this board is from another game? Searching through the MAME code, there is a comment that Universal game #8011 is Zero Hour. Luckily, a manual and schematics are available for Zero Hour. The starfield board is the same! In Zero Hour, this board provides both color generation and stars. The missing chips in Space Raider disable the color generation part, since that's already on the main board. Anyways, I added preliminary support for the scrolling stars to MAME, and it looks right. I need to measure a few more things to get the timing exact. When I'm done with Space Raider, I'd like to add the stars to the Zero Hour / Red Clash driver, since it's missing there as well.
- 0.72: Fixed dipswitches in Zero Hour.
- 0.55: David Haywood added Zero Hour (Universal 1980).
- 30th August 2001: Nicola Salmoria improved Zero Hour.
- 27th August 2001: David Haywood added Zero Hour to the Red Clash driver, but it has some graphical issues.
