0.60 [EMUL8, Dan Boris]
WIP:
- 0.141u3: hap fixed sound tones never stop playing in Hit Me.
- 0.139u4: Siftware added Hit Me (set 1). Changed description of 'Hit Me' to 'Hit Me (set 2)'. Renamed (hitme) to (hitme1).
- 0.135u3: Fabio Priuli added driver data struct and save states to Hit Me driver.
- 0.129u5: Incog changed description to '21 (Mirco)' andyear to 1976. Renamed (mblkjack) to (m21).
- 0.100: Aaron Giles fixed graphics decode in Hit Me.
- 0.80u2: Aaron Giles fixed bug in 555 timer that led to whiny noise in Hit Me. Removed 'Game Speed (analog)' and 'Card Width (analog)' dipswitches.
- 17th March 2004: Aaron Giles - Derrick Renaud managed to figure out why Hit Me was whining, which is a relief because at 22kHz it sounded pretty annoying.
- 0.80u1: Aaron Giles added discrete sound support for Hit Me. Fixed incorrect video (missing scanlines and inverting logic). Added controls to handle card width and game/sound speed. Cleaned up memory maps. Changed visible area to 320x190 and added dipswitches 'Game Speed (analog)' and 'Card Width (analog)'.
- 9th March 2004: Aaron Giles - I've been talking to Derrick Renaud about the discrete sound system and how I can start getting involved. Derrick suggested to look at Ramtek's Hit Me, but it had some tricks all its own. I had to add a D-type flip-flop primitive. I think I've finally got it working now. While I had the schematics handy, I took some extra time to fix up some video and memory map issues in the driver.
- 0.74u2: Added clone Black Jack (Mirco).
- 27th September 2003: MASH added clone Black Jack (Micro).
- 0.60: EMUL8 and Dan Boris added Hit Me (RamTek 1976).
