1) Yes not HH for this board, but YES a prototype works fine for ALL MA-216 sound boards : MGOW ... CAVEMAN, and KRULL video GAME !
Due to connector and power supply différences we can't have a single board for the three types of boards.
For the moment all sounds works "as original" for all games, speech is just "ignored" as if the SC-01 is not mounted, the next challenge is to support speech !
We can add REAL SC-01 on board, (it works done on prototype board), BUT due to the availability of this component, it wil be more reasonnable to ... Emulate it !
2) No ... Pascal board uses programmed processor ST7xxxx.
So it is unremplacable as well !
And not at all titles are supported. (HULK-500, three SYS80B)
In our board the REAL components are implemented in the FPGA, (Even the EARLIER versions of R6530) there is no samples, so quality is the SAME as originals.
To be continued ...
