Re: [hatari-users] PSG/microphone volume (Falcon)

[ Thread Index | Date Index | More Archives ]


I confirm Thomas's words.

ff8939 should work and is implemented.
I've never implemented the channels overflow (I didn't have any example to understand and test this)

If you encounter  some problems with these 2 addresses, please, don't hesitate to send a little example with the explanation of what is expected.

Is the PSG/microphone input volume correctly handled? I'm working on a
project which use this, and while it's working correctly on a real
Falcon it seems to be ignored on Hatari (2.2.1, Linux).

I'm talking about the $ff8939/$ff893c registers.
Looking at Crossbar_InputAmp_WriteByte() which handles ff8939 it seems
that there is some code in place to handle this. But
Crossbar_CodecStatus_WriteWord() which handles ff893c does not seem to
do anything ... maybe Laurent knows more?
