- 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
Archimedes 305, Archimedes 440, Archimedes 3000, Archimedes 410/1, Archimedes 420/1, Archimedes 440/1, Archimedes 540, Acorn A5000, Acorn A4, Acorn A4000, Acorn A5000 Alpha
- renamed a310->aa310 to avoid conflict with Amiga machines
- added all missing OS releases Arthur 0.30, RISC OS 2.01, RISC OS 3.00, RISC OS 3.10, RISC OS 3.19 (German)
- all machines default to OS (Arthur, RISC OS 2, RISC OS 3) they were shipped with
- corrected ROM labels/locations
- added default CMOS to boot to desktop
- mapped Acorn A4 Power Management extension
the bios and turn off JP1 as part of the installation. A v1 bios flash is included, but
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]
Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
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.
