you aren't forced to use it. [smf]
Moved G-NET protection out of ATAFLASH and into individual devices for each type of card [smf]
Implemented enough analogue control reading on ZN1/ZN2 for RC De Go & Go By RC [smf]
Fixed ZN1/ZN2 DSW descriptions [smf]
Added build dates and times to G-NET game descriptions [smf]
New machines added or promoted from NOT_WORKING status

- Emulated the Acclaim RAX sound board, adding sound to Batman Forever and NBA Jam Extreme [Phil Bennett]
- Hooked up extra NVRAM in NBA Jam Extreme [Phil Bennett]
with the following games
Time Scanner (TS 2.0, Magnet System, prototype)
Exzisus (EX 1.0, Magnet System, prototype)
Xain'd Sleena (SC 3.0, Magnet System, prototype)
this is a checkpoint, there is a sizeable ToDo list but I think this is a good enough state for initial inclusion before working out the remaining issues. ArcadeHacker has the hardware working for questions etc.
I would especially appreciate help with sound (haven't a clue how it hooks up, tried lots of things, no luck) and some help in going over the CPU comms, especially with the sprite CPU as I think I must be missing something important. Likewise help from somebody more familiar with the floppy code from MESS so that it can use that, I had no luck in getting it to work with the copy protection or from a rom region, I've kept all floppy related code in a device so it's very easy to swap out so for now what I've got isn't intrusive.
note, very weird idea for a system, they've ported 3 arcade games from other manufacturers, original titles were advertised, but it's likely nothing more of the system exists.
the system uses 5 PCBs, one Z80 on each and instead of having dedicated sprite / tilemap chips they have the Z80s doing software rendering, using 8bpp framebuffers. 2 of the boards are for background planes, 1 of the boards is for sprites. The hardware has various memory expansions which look like afterthoughts as they're addressed in strange ways.
ataxx: Fixed missing sound channel caused by one dac not being hooked up and one dac being hooked up to two addresses.
bestbest: Fixed high pitch screech caused by incorrect addressing (two dacs weren't hooked up and two were hooked up to two addresses).
cchasm: Fixed static noise generation caused by feeding the same bit to both dacs.
cheekyms: Slightly improved sound by implementing sound triggers as 8 x 1 bit dacs instead of 1 x 8 bit dac.
galeb: Fixed sound by implementing it according to http://www.deltasoft.com.hr/retro/galebemu.htm & implemented enough of LOAD/SAVE to stop it hanging.
hard drivin: (all games in driver) Improved 12 bit controls, although centre still goes out of sync.
mea8000: Converted to a sound device.
megaphx: Fixed noisy samples due to wrong format.
microvsn: Fixed sound pitch caused by incorrect usage of write_signed8().
seicross: Changed to a 4 bit dac as samples are packed nibble.
spaceg: Preliminary sound using space invaders samples.
suna8: Changed to a 4 bit dac as samples are packed nibble.
vcombat: Fixed static during machine gun fire due to incorrect dc offset removal.
vectrex: Fixed noisy samples due to wrong format.
wheelfir: Fixed sound, eeprom & analogue steering wheel and brake pedal.
this is similar to, but not identical to goldstar.cpp / skylncr.cpp. it might be possible to merge it in, however my gut feeling is that said driver should be split up into different machine types all using some generic but fleixlbe video device that can handle these 8x8 tiles, 8x32 reel cases as most of them are based on the same basic concepts, just with their own tweaks.
reels, sounds, inputs are not hooked up here.

displays the game image, upside down, no palette for now, no inputs for now, no sound for now, going to continue work on it.
