A new PS4 emulator is in development from the creator of RPCS3, though it's likely years away from running games

Exciting news, PC gamers: We now have yet another way to pine for Bloodborne on PC. A new emulator project appeared on Github on Saturday from the creator of excellent PlayStation 3 emulator RPCS3, this one named RPCSX. Its target platform? The PlayStation 4—an exciting prospect, since Sony's PC ports inevitably won't cover the system's entire library. For the foreseeable future, though, pining after PS4 exclusives like Bloodborne is all we'll be able to do, as the emulator is likely years away from making commercial games legitimately playable.

There are several reasons to temper your expectations here, including the fact that RPCSX currently isn't being built for Windows. «This is an experimental emulator for PS4 written in C++ for Linux. It's NOT possible to run any games yet. It's also unknown when it will become possible,» says the Github page.

RPCS3 has been in development for a decade, and still 30% of the games in the PS3's library «either can't be finished, have serious glitches or have insufficient performance» in the emulator. Since RPCSX is just getting started, it could be a year or more before games so much as boot, let alone run smoothly. There are reasons to be optimistic here, though: RPCSX is being led by the same programmer who started RPCS3, with a couple other longtime RPCS3 contributors also on board. The PS4's x86 architecture is essentially the same as a modern PC's. Even though it does some things differently (memory is shared between GPU and CPU, for example), it should be much easier to translate than the PS3's notoriously complex Cell processor.

There will still be a million problems to solve, though: emulating the PS4's OS, dealing with encryption, shaders, building a UI, eventually adding
