When gamers think of Sonic Unleashed, they usually picture the high-octane HD version on Xbox 360 and PlayStation 3, or they debate the controversial "Werehog" mechanics. However, lost in the shuffle of the 2008 release window was the PlayStation 2 and PlayStation Portable (PSP) version.

Q: Is Sonic Unleashed on PSP the same as Sonic Unwiished (Wii/PS2)? No. Sonic Unwiished (fan name) refers to the Wii/PS2 versions, which have 3D hub worlds and different level geometry. The PSP version is its own 2D engine.
Q: Can I play the Sonic Unleashed PSP ROM on a PS3? Yes, if your PS3 has Custom Firmware (CFW) and you install PSP Launcher. But performance is worse than PPSSPP on a PC.
Q: Is there an English patch for the Japanese ROM? The Japanese ROM includes full English text if you set your PSP/emulator region to USA. No patch needed.
Q: Why does my Sonic Unleashed PSP ROM crash on stage 2-1? You likely have a bad dump. Re-download from a reputable source. Corrupted ISOs often fail on the first Werehog stage.
