Gauntlet Legends/Dark Legacy running at 4x speed when auto frameskip is disabled

[TheRetroCarrot]

I'm having an odd issue with just these 2 games. If I disable auto frameskip and set frameskip to 0 it runs at 400% speed and audio stutters all over the place. Auto frameskip makes it playable but it takes a little bit to stabilize and I'd much rather avoid it.

The PC should be able to handle these games without issue I'd think, it's a 9700k, 280x, 32GB ram. Any idea what I'm missing here? I've come up with nothing through my googling and forum searches.

Thank you.

It runs Gauntlet Legends 400%?

What a time to be alive.

Lol yes, I actually figured out a solution, but why it's a solution makes no sense to me.

Setting syncrefresh 0 manually in the game specific ini files corrects this. The problem with this, is that mami.ini already has syncrefresh set to 0. I can find absolutely no other ini files in the load order that would overwrite this setting. It's like GroovyMame is ignoring my changes to mame.ini, I also had to specify keepaspect 0 manually for all my games, and also coin_impulse 15 for my phototransistors to register properly. For some reason setting these in the mame.ini did not work.

I also would have expected to see issues in other games (I've configured about 100 of them so far) if syncrefresh was actually registering 1 by default. Not really sure how to verify what setting I'm getting normally.

Any ideas why this might be happening?

This would be probably Your answer. I personally didn't test it so far but I'm sure this will solve problem.

You nailed it, .265 fixed my issues!

Only thing I still can't figure out is why keepaspect and coin_impulse from the mame.ini are ignored. Not the biggest deal as I've already copied per game inis for every game I have loaded, but it'd still be nice to understand why.
