Q: I’m not seeing LRPS2 in the core list.
A: The core is probably not available for your platform. It is available for Windows, Linux (x86_64), and MacOS. It is NOT available for Android or iOS, nor for ARM Linux. If you’re sure it should be there for your platform and you’re still not seeing it, try updating your core info files via the online updater.
Also, don't necro-post.
