The RPCS3 team has hit another compatibility milestone, and this one’s a big deal for anyone who grew up with a PS3. The open source emulator now lists 75% of its tracked library, 2,681 out of 3,559 games, as “Playable.” That’s up from 70% back in January, so the project added roughly five percentage points of coverage in about six months.
“Playable” in RPCS3’s own terms means a game can be finished start to finish with acceptable performance and no game-breaking glitches. It doesn’t promise a flawless run. Some titles in that tier still have minor graphical hiccups or audio quirks, but nothing that stops you from reaching the credits.
While that is great news, not everything has cleared the bar yet. The Last of Us, God of War III, and Metal Gear Solid 4 are still stuck in the “In-Game” category, meaning they load and run but hit serious glitches or performance issues severe enough to block a full playthrough. It makes sense that Sony’s biggest, most demanding PS3 exclusives are the last ones to fall in line, since those are the games that pushed the Cell architecture hardest in the first place.

There’s a second, quieter development worth noticing, too. RPCS3 contributor capriots recently merged a change that reimplements cellSysmodule, a PS3 system component games use to manage internal libraries, without relying on Sony’s original firmware code.
Instead, RPCS3 now handles it through high-level emulation, essentially rebuilding the function in its own open source code rather than borrowing Sony’s. It’s a small piece of a much bigger puzzle, but it edges the emulator closer to a long-term goal: running PS3 games without needing Sony’s firmware installed at all.
It’s worth being clear here that that day hasn’t arrived. RPCS3’s setup guide still requires official PS3 firmware for other proprietary dependencies, and nobody should delete their firmware files based on this alone. It’s also a reminder that performance still varies a lot depending on the hardware running RPCS3, so a higher compatibility number doesn’t mean every game runs smoothly everywhere.

Question #1
Which popular PS3 exclusives are still listed as In-Game (not Playable) on RPCS3 right now?
According to the article, The Last of Us, God of War III, and Metal Gear Solid 4 are still listed as In-Game (not Playable) on RPCS3 right now.
Answered
Question #2
How many PS3 titles does RPCS3 currently track and how many are marked Playable?
RPCS3 currently tracks 3,559 PS3 games, of which 2,681 are marked “Playable.” “Playable” means a game can be finished start to finish with acceptable performance and no game-breaking glitches.
Answered
Question #3
What change did contributor capriots merge regarding cellSysmodule and why does it matter?
Contributor capriots merged a change that reimplements cellSysmodule, the PS3 system component for managing internal libraries, using RPCS3’s own high-level emulation instead of relying on Sony’s original firmware code. This matters because it replaces proprietary firmware dependency with open source code, edging the emulator closer to the long-term goal of running PS3 games without needing Sony’s firmware and aiding preservation of the platform.
Answered
Question #4
Can I remove Sony’s official PS3 firmware files now that RPCS3 reimplements cellSysmodule?
No. RPCS3 reimplemented cellSysmodule in open source code, but the emulator still requires official PS3 firmware for other proprietary dependencies, and the setup guide continues to require Sony’s firmware files, so you should not delete them.

If we look at the timing, this lands right as Sony winds down the PS3 and PS Vita PlayStation Store, part of a bigger move away from the console’s digital storefront. That makes RPCS3’s preservation work feel more urgent than it might have a few years back. Between the compatibility jump, the recent Cell CPU performance boost, and now this firmware work, the emulator looks to be inching toward something close to full PS3 preservation, even if total playability is probably still a ways off.
