chqflag: MAME ROM Information.
History:
Chequered Flag (c) 1988 Konami.
An overhead-view racing game featuring rotational sprite scaling. The player races over a series of twisting courses, trying to reach the finish line before the timer expires.
Chequered Flag includes a Pit-stop facility, a feature that had appeared a year earlier in Taito's 'Continental Circus'. Should the player's car sustain too much damage, a pit-stop must be made to implement repairs. A 'damage meter' at the bottom of the screen shows the severity of the damage; highlighting what car components are in need of repair; Engine, Front Tires, Rear Tires and Brakes.

Bugs:
- chqflag chqflagj: I noticed the original PCB has many slowdowns and also looses frame rates (seems to run at 25hz) when there are 3/4 opponent cars on the same screen. This doen't happen on MAME. Kold666 (ID 03982)
WIP:
- 0.143u8: Kanikani fixed coinage DIPSW using Konami common setting in Chequered Flag.
- 0.142u3: Angelo Salese fixed protection read-back registers 0x07 and 0x0e / 0x0f in K051733 math chip, finally fixing gameplay issues in Chequered Flag. Made K051733 RNG to behave like an adder. Removed deprecat.h dependancy and updated irqs accordingly for Chequered Flag.
- 29th April 2011: Angelo Salese - While doing deprecat.h clean-ups (basically conversion of irq systems in old drivers) I've stumbled across one of my oldest nemesis... Chequered Flag by Konami. After some grinding of my teeth and a LOT AND HALF of DASM code studying, I've finally nailed it down, it was mostly a rather silly bug with the protection device, checking that a check was true on a port by checking that all the bits were high instead of just one like one could imagine... Note: I'm not entirely sure that the protection is COMPLETELY emulated, if you know the original game and notice something wrong just let me know via the public channels, thanks in advance.
- 0.136u1: Fabio Priuli added driver data struct and save states to Chequered Flag.
- 0.135u4: Fabio Priuli updated Chequered Flag to use Konami video devices.
- 0.131u1: Angelo Salese added engine noise hook-up to Chequered Flag. Phil Bennett fixed nested NMIs on Chequered Flag sound CPU, this fixes the sound loops and the music tempo. MooglyGuy merged memory maps in Chequered Flag.
- 0.129u6: Mr. Do added built-in layouts for Chequered Flag.
- 0.126u5: Aaron Giles fixed memory leak warning in Chequered Flag.
- 0.126u4: Fabio Priuli added DIP locations for Chequered Flag.
- 0.122u5: Corrado Tomaselli verified/corrected frequencies in Chequered Flag. Changed YM2151 clock speed to 3579545 Hz.
- 0.105u3: Aaron Giles fixed bank switching in Chequered Flag.
- 0.84u5: Replaced Stick controller with Paddle.
- 0.74: Some improvements to Chequered Flag protection and sound [Angelo Salese]. Changed YM2151 clock speed to 1789772 Hz.
- 11th September 2003: Angelo Salese submitted an update to the Chequered Flag driver, fixing enemy appearing, music tempo and steering.
- 0.53: Nicola Salmoria added real shadows in some Konami games (88 Games, Chequered Flag, X-Men, Asterix, Surprise Attack, Sunset Riders, etc.).
- 7th August 2001: Nicola Salmoria adjusted the tilemap system to work better with Chequered Flag.
- 0.37b13: Manuel Abadia added Chequered Flag (Konami 1988) and clone (Japan).
- 22nd February 2001: Nicola Salmoria got Chequered Flag working, but background / sprite graphics priority control is not implemented yet.
- 24th September 2000: Guru - Redumped the bad roms for Chequered Flag. The entire dump is now good, but unfortunately, the graphics glitch is still present (though now only on the road). Oh well, I guess it's up to MAMEdev to fix it. Special thanks to Andrew Slorach for buying this PCB and sending it.
- 0.37b1: Manuel Abadia added Chequered Flag and clone (Japan) (Testdriver). Known issues: Some background tiles are missing. Hopefully this is because of the bad ROMS. The enemies appear and dissapear randomly because of the K051733 protection. The sound is not working properly.
