Mame 2010: fast forward doesn't work

hello folks. why on mame 2010 cores fast forward doesn’t work? on mame 2003 and Current it works.

i use retroarch 1.9.14-2 on ArchLinux (kernel 5.15.15-1-lts) with openGL

Framerate might be throttled internally instead of letting libretro deal with it.

on “Set frameskip” option i have set 0. i have tried to set “automatic” but fast forward still doesn’t work.
