WIP:
- 0.136u4: Fabio Priuli added driver_data struct and save states to Mazer Blazer driver.
- 0.131u3: Angelo Salese cleaned-up the Mazer Blazer driver. Changed Z80 CPU2 clock speed to 3579545 Hz and the 2x AY-3-8910A to 1789772 Hz.
- 0.131u1: Angelo Salese merged memory maps in the Mazer Blazer driver.
- 0.130u2: Demoted Great Guns to have the GAME_NOT_WORKING flag.
- 12th November 2006: Mr. Do - We have Great Guns bezel, thanks to scans by Aaron Giles and cleanup by Ad_Enuff.
- 0.106u1: Changed Light gun input to Stick.
- 0.71u2: Jarek Burczynski added Great Guns (Stern 1983). TODO: Figure out what really should happen during VCU test in Great Guns (patched out at the moment, btw. Mazer Blazer doesn't test VCU). Known issues: Sprites leave trails. Sprites should be transparent (color 0x0f). Screen flickers heavily in Great Guns (double buffer issue?).
- 11th July 2003: Jarek Burczynski added another graphics mode to the Mazer Blazer and Great Guns driver, making Great Guns playable although with some graphics glitches, but Mazer Blazer is not very playable because of missing collision detection.
- 20th January 2003: Jarek Burczynski sent in a work-in-progress driver for Mazer Blazer and Great Guns, they have a variety of problems with graphics and sound.
