As tittle suggests, we got another open source PS5 emulator. Key differences are targeting games compatability and a cross-platform support: currently emulator supports and builds for MacOS, Windows and Linux. As I understand, this project also relays on Kyty, similarly to KytyPS5 fork.

Current progress includes loading Demon Souls up to it's menu ( image source)
