There's a video on YouTube that link to a Flatpak and a standalone application that allegedly can run PS4's Megaman Legacy on Linux distributions.
I have some doubts it's a full PS4 emulator, but I can confirm that it runs, or at least it requires, the "NES emulator" that's inside the PS4 package.
I've done some brief digging on that title (https://www.reddit.com/r/Megaman/comments/3igzxk/mega_man_legacy_collection_is_a_fancy_emulator) and I would say the author created an "Eclipse Engine" emulator (cf. that Reddit thread) instead of a "HLE PS4" emulator as it's a multiplatform title, anyway the hack is neat as it requires the eboot.bin to launch, so it gives the illusion to run a PS4 emulator... ^__^;
For sure I would love to know more details.
