WIP:
- 9th January 2009: Mr. Do - A couple versions back, I missed that Haze had fixed the LED in Gridiron Fight (which is needed to select plays). I've now added in Control Panel artwork for it, thanks to the BYOAC/CAG artwork. Putting in the whole CP artwork leaves the screen kinda small, so I added in a "mini/cropped" version also. If I were going to do it completely right, I'd have the CP at the top (for Player Two) and the bottom, which would make the screen even smaller. So for now, the left LED is Player One, and the right LED is Player Two.
- 0.128u6: David Haywood added proper artwork for the LEDs in Gridiron Fight.
- 0.122u4: David Haywood fixed graphic/sprites anomolies.
- 0.59: Added dipswitches 'Start Credits (P1&P2)/Extra', 'Formation Time (Defense)', 'Timer Speed', 'Formation Time (Offense)' and 'Demo Sounds'.
- 0.36b9: Changed clock speed of the 2x AY-8910 to 1536000 Hz.
- 0.35b9: Added 3rd and 4th player input.
- 0.34b8: Changed description to 'Gridiron Fight'.
- 0.34b4: Replaced ADPCM sound with MSM5205.
- 0.34b1: Nicola Salmoria added Gridiron Fight (Tehkan 1985). The original game uses a LED display to show the number of the formation selected. This is emulated by placing a character in the corner of the screen. Known issues: The game sometimes resets, though not as often as Tee'd Off. Sprite/foregound priority is not emulated. This makes the arrow showing the position on the field map not visible. Dipswitches not verified.
- 25th July 1998: Dumped Gridiron Fight.
