add Roland CM-32P driver (#5876)
* add (non-working) CM-32P driver * CM-32P: make booting test mode sort of work (nw) * CM-32P: fix initialization, working test mode (nw) - test mode now boots properly and shows error report - test mode can be enabled/disabled - RCC-CPU check passes - PCM ROM check passes, PCM card check fails (requires SN-U110-04 card) * CM-32P: add research notes (nw)

Roland CM-32P driver
|
||||
|
||||
Driver by Valley Bell
|
||||
|
||||
Thanks to KitsuWhooa for the PCB layout diagram and part list.
|
||||
|
||||
|
||||
Notes:
|
||||
- When booting, it does a basic check by writing values 0..0xFF to 0x108A.
|
||||
It then expects (value & 0x03) to be read back from 0x1080 and (value) to be read back from 0x1081/0x1082.
|
||||
The routine for doing the check begins at 0x4686.
|
||||
Succeeding means it ends up at 0x4801.
|
||||
- When in test mode, the firmware gets stuck in the loop at 0xBB06, waiting for Interrupt #5 (calls 0x4014) to fire.
|
||||
It gets there by calling function 0xBBBB, which writes text (address w@0x40, num characters b@0x43) to the LCD screen.
|
||||
This can be worked around by setting b@BB2D = 03.
|
||||
- The firmware gets also stuck in the loop at 0x7D70, waiting for Interrupt #8 (calls 0x4020).
|
||||
This might be related to finding the best free voice?
|
||||
You can exit the loop by setting b@7D80 = 00.
|
||||
- Test Mode shows the results of 4 checks:
|
||||
1. SRAM check
|
||||
2. MIDI IN/OUT check
|
||||
3. PCM ROM and card check
|
||||
4. RCC-CPU check
|
||||
Errors in check 2 and 3 are "not abnormal".
|
||||
In order to make check 2 pass successfully, you need to connect MIDI Out with MIDI In, creating a loopback.
|
||||
Check 3 requires the SN-U110-04 PCM card ("Electric Grand & Clavi") to be inserted in order to succeed.
|
||||
- In order to access the built-in PCM ROM (IC18), the CPU asks the sound chip to read offsets 0x000000 .. 0x07FFFF.
|
||||
The PCM card is accessed via offsets 0x080000 .. 0x0FFFFF.
|
||||
The additional PCM ROMs are mapped to 0x100000 .. 0x17FFFF (IC19) and 0x200000 .. 0x27FFFF according to the sample table in IC18.
|
||||
- The sound chip has 32 voices. Voice 0 is reserved by the firmware for reading data from the PCM ROM.
|
||||
The firmware allocates voices from back to front, i.e. voice 31 first.
|
||||
|
||||
|
||||
TODO:
|
||||
- actual sound emulation
|
||||
- add PCM card support
