ShadPS4 est un émulateur préliminaire de PS4 pour Windows et Linux écrit en C++ créé par Shadow (d’ou il tire son nom), auteur et contributeur de projets prestigieux comme PCSX, PCSX2, PCSP, JPCSP, Arcadeflex, RPCS3…
Les changements principaux en résumé:
Surprise! Bet you didn’t expect a release from me, did you? 🙂 Well you all asked for a miracle, and here I am, providing one. Anyways, this release is dedicated to one of our not-so-new dev, LNDF, who is responsible for a significant amount of the new GPU code, such as implementing Direct Memory Access for video memory. This isn’t a solo endeavour though, there were far more updates to the emulator from the rest of the team as well, improving compatibility across well-known titles such as P.T, Driveclub, inFAMOUS, Bloodborne, The Last Guardian, Shadow of the Colossus (although this one still can’t boot without hacks) and more:
