DAC WIP, started documenting the DACs in use. [smf]
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.
