Implement TT5665 emulation (#6841)
* Implement TT5665 emulation Similar as OKIM6295, but with Support more ROM capacity and phrase spaces, 2 sound outputs used in bowltry, igs_m036 (for some hardwares with TT5665, ex: cjddzsp) bowltry.cpp: Fix game name (BOWLING TRY! in both poster and PCB) * bowltry.cpp: Typo * Fix endline * tt5665.cpp: Reduce unnecessary argument

****************************************************************************
|
||||
|
||||
Tontek TT5665 ADPCM chip:
|
||||
|
||||
Command bytes are sent:
|
||||
|
||||
1xxx xxxx = start of 2-byte command sequence, xxxxxxx is the sample
|
||||
number to trigger
|
||||
xxab vvvv = second half of command; the ab bits are voice number,
|
||||
the x bits are high bits of sample number, the v bits
|
||||
are volume
|
||||
|
||||
0abc d000 = stop playing; one or more of the abcd bits is set to
|
||||
indicate which voice(s)
|
||||
|
||||
Status is read:
|
||||
|
||||
???? abcd = one bit per voice, set to 0 if nothing is playing, or
|
||||
1 if it is active
|
||||
|
||||
ADPCM data and volume is compatible with OKI MSM6295, but some Command
|
||||
byte is slightly different.
|
||||
|
||||
Compares to other Tontek OKI MSM6295 derivatives:
