Sometimes it seems that Sony itself is a PS4 hacker’s best friend. In January, we wrote about how hackers were taking advantage of the system’s built-in PlayStation Classics emulator to get arbitrary PS2 games running on unlocked hardware. Now, it seems a PSP emulator buried in a “remastered” PS4 release could provide a new way to get upscaled versions of the portable system’s games running on your TV.

The PS4 game in question is PaRappa the Rapper Remastered, a bare-bones, upscaled re-release of the ’90s PlayStation rhythm game. Earlier this week, GBATemp user KiiWii posted his discovery that the PS4 game uses an in-built PSP emulator to run a copy of the 2007 PSP version of PaRappa rather than running new code specifically ported to the PS4.

The only apparent difference in the PS4 remaster is an included 4K texture package that makes the game look good on a modern television. We’re reminded of similar fan-made texture packages that can already improve the look of everything from N64 and PS3 games to Wii U games via PC-based emulators.
