Killzone runs almost perfectly in PCSX2 2.4 (except for short freezes about once a minute).
In RetroArch running the LRPS2 core, It freezes at the "Playstation 2" screen right before the game's content starts. Just a black screen with no audio.
Running USA BIOS v01.70 (25/03/2003)
I've got an Nvidia card, and I read it was recommended to use the "vulkan" renderer driver, which I do. Tried every renderer that LRPS2 comes with.
Nightfire and Crash Nitro Kart run with no issues in LRPS2.
