Metal Slug 6 slow and sound crackling in Retroarch 1.7.8v4 / flycast

Hi,

MS6 is now unplayable due to a big stuttering and sound crackling. Not sure if it occured with retroarch 1.7.8v4 or after a flycast update.

Seems like another duplicate of https://github.com/libretro/flycast/issues/657 and https://github.com/libretro/flycast/issues/653

Whole story short : don’t use the old non-MAME naomi dumps, they have been deprecated a long time ago.

Some more results here, 3700x I’m using the mame roms for mslug6, fresh setup of retroarch, latest flycast.

With Hard GPU Sync on, 0 frames it barely runs at full speed, with 1 frame it is super fast.

Is this intended behavior?

bye, Michael

That did the trick. Big thanks!
