Sound issue in Mega Turrican #2

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. pick MAME core in FM options
2. load "Mega Turrican" (any version)
3. go into Sound test menu
4. play Track 03,06,09...

What is the expected output? What do you see instead?

One of the FM channel has a wrong output. After investigation, it is either
on channel 1 or channel 4. Each problematic track use FM algo #0 with
feedback value #7. Operator settings are also the same (see attached file).

Muting Operator 2 output make the annoying sound disappear.

Please use labels and text to provide additional information.

Fixed in current SVN

This was a problem with some inaccuracy with Enveloppe Generator when AR=0x7f 
and SL=0
