Playing PSP, PS2, and PS3 Games on PC: Emulation and Streaming Options

Yes, but difficulty varies by generation.

PSP Games → PC: Easy

• PPSSPP (Windows/macOS/Linux/Android/iOS): Near-perfect compatibility. 1080p/4K upscaling, texture packs, post-processing, save states, cheats, multiplayer (adhocserver). Best way to play PSP today.
• Legal: Dump your own UMDs (CFW PSP → ISO) or buy digital (PSNpkgsDecrypt + PKGj).

PS2 Games → PC: Easy

• PCSX2 (Windows/Linux/macOS): High compatibility (>98%). Requires decent single-thread CPU (Ryzen 5000 / Intel 12th gen+ for full speed). Features: upscaling, widescreen hacks, texture filtering, cheats, netplay.
• PlayStation Now (Premium): Streams ~50 PS2 titles. 720p/60fps. Requires 15+ Mbps. No ownership.

PS3 Games → PC: Hard (But Improving)

• RPCS3 (Windows/Linux/macOS/BSD): Open-source PS3 emulator. ~65% playable (Ingame/Playable). Demands high single-thread CPU (7800X3D / 13900K ideal), Vulkan GPU, 16+ GB RAM. Demon's Souls, MGS4, RDR, TLOU, Uncharted now playable.
• PlayStation Now (Premium): Streams ~300 PS3 games. Same requirements. Latency-sensitive.

Legal & Practical Notes

• BIOS / Firmware: Must dump from your own console (PS2 BIOS, PS3 dev_flash). Downloading = piracy.
• Discs: PS2/PS3 discs need compatible drives (PS2: some LG/ASUS; PS3: BD-ROM). Easier: dump via CFW console.
• Performance: Emulation ≠ native. Shader compilation stutters, audio glitches, game-specific bugs persist.
• Saves: Transfer via PS3 Memory Card Adapter (PS2) or CFW homebrew (PS3).

Verdict

PSP/PS2: Emulate on PC (PPSSPP/PCSX2) — superior to original hardware.
PS3: RPCS3 if you have a beast CPU; else PS Now streaming or original hardware.
