Orbital #5: Heartbeat
Brief status update: The project is still alive.
Just not sources/binaries/screenshots yet.
Both the SeaBIOS/GRUB forks have been removed in favor of using decrypted 80010002 images. During the past year massive progress has been done in both the emulator and hypervisor, although we are not ready yet to share details, we can provide a sneak peek in what's about to come for PS4 hackers/modders in terms of introspection and debugging capabilities. More news to follow soon!
