Short answer: Apollo Save Tool is a PlayStation 3 homebrew application. There is no official RPCS3 build of Apollo, and the developer publishes no emulator support or guidance. Anything below is the practical explanation of what that means.
Why People Ask
Apollo’s PS3 build does things emulator users want: re-sign saves between accounts, unlock copy-protected saves, convert PS1/PS2 saves to PS3 .PSV format. It’s natural to wonder whether you can just run it inside RPCS3, the PS3 emulator, and skip owning the console.
The Practical Reality
- Apollo is distributed as a PS3
.pkghomebrew. Emulators run homebrew with varying success, but Apollo leans on real-console specifics — firmware modules, account data (PSID/IDPS/Account ID) read from an actual PS3 user environment, HDD partition layout — that an emulator only approximates. - The developer’s documentation covers real hardware only. If something misbehaves under emulation, there is no support channel for it, and this site won’t pretend otherwise.
What RPCS3 Users Do Instead
RPCS3 keeps its saves as plain files inside the emulator’s virtual hard-disk folders on your PC. Day-to-day save handling there is ordinary file management: copy the game’s save folder out, back it up, restore it later. Cross-account and cross-console conversions are where a real PS3 with Apollo (or a PS3 tool on PC such as Bruteforce Save Data — see Apollo vs Bruteforce) still earns its place.
The Bottom Line
If your saves live on a real PS3 (or need to end up on one), Apollo on the console is the supported path — install guide here. If your saves live purely inside RPCS3, they’re files on your PC; back them up like files (our 3-2-1 backup routine applies unchanged).
