They're definitely related. Separate reports for them is fine though.

Sorry, I'll leave to others better than me in disassembling CPUs the job. I'll spent a lot of time on this issue but without luck.

I tried to check this with OG's latest changes but I don't have a good enough ear for audio stuff. Could anyone check if it's fixed?

Where are Olivier Galibert latest changes? I see nothing in mameinfo. The closest thing I see are the reported changes made to The Simpsons in mame 0.222 WIP.
It would be cool to have this old issue fixed.

@Osso
I has tested in current version.
The bug is in current version.
Have others Konami games with sound issues and some others games of others companies with sound tempo issues using the Yamaha sound.
Sounds simple to fix, but the work is where to figure the issue.

Unhappily has hackers trying to destroy current generation console for "glory", but the "glory" is temporary and soon will lose that status. Emulate current console is an terrible problem.
Hey "hacker" that is trying emulate current console .... Join in MAME Team and stop with it.

MetalGod: the chip (K053260) affected by Galibert's changes you mentioned is used by both The Simpsons and Vendetta.

Sorry, I can't test it. I'm too bad at compiling wip versions of mame. It always fail somehow, no matter I follow step by step the documentation for it.
