- Uses the standard 6840 PTM core for sound generation
- New MM583 Noise Generator device
- New DAC-76 DAC sound
- Use resistor network values for colors
- Use bankdev device for banking
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.
as the pull request seems to have gone dead I refactored his changes into a new device derived from the 7759 rather than adding the Fifo into the 7759 (due to Aaron saying it doesn't exist there)
it's possible the custom chip that Pico uses has said logic built in somehow as it's not a plain 7759 afaik.
make TARGET=mess -j19
will generate all needed files and build MESS, while developing you can use
make TARGET=mess COMPILE=1 -j19
to prevent rebuilding of make files.
Build system have automatic generate of dependencies so will do incremental builds fine.
make clean
will remove all generated files/projects and obj files
