Playstation suddenly slower since 4.0 to 4.1 upgrade

[BingoLittle]

Hi everyone,

I recently upgraded from RetroPie 4.0b to 4.1 and, while basically everything else went smoothly, I noticed Playstation games suddenly run very slow. Before the upgrade Tekken 1 and Tekken 2 ran perfectly - now they run as if in slow motion. What is strange is that I am getting 60FPS according to RetroArch, and the menus and everything else (i.e. the Galaga intro game, as well as the intros) run perfectly. As soon as the gameplay begins, however, I get very slowed down gameplay, akin to slow motion.

Any ideas what may be happening?

As far as I remember, I did not have this speed hack enabled:

pcsx_rearmed_neon_enhancement_enable = "enabled"
pcsx_rearmed_neon_enhancement_no_main = "enabled"

I am running a Pi 3 (on a CRT if that's relevant).

Many thanks for any help!

@BingoLittle update all packages. Already fixed.

Great, I'll do that.

What package in particular should I update if I didn't want to update all packages?

Thanks a lot for the help.

@BingoLittle RetroPie-Setup script then the lr-pxsx-rearmed.

Thanks a lot, that did the trick.
