Here are two videos from YouTube showing a "working" PlayStation (PSOne) emulator for the PSP. We traced back the source of these videos and we stumbled upon an article posted by magixien over at PSP-Generation. It seems a team of programmers have announced as early as August 4 that they are working on a PlayStation emulator for the PSP called PSXP (portable PSX).

Based on the small progress report, the team is looking at 25-30 fps. They are still mum about the other features of the emulator, but they did say that an early version of the emulator works fine even if the frame rate is only at 14 fps.

Well, several days later, the team posted the videos for your viewing pleasure. It's said to be a "proof of concept", perhaps to silence the unbelievers. Of course, the PSP community would be divided (those who'd say it's real vs. those who'd say it's fake) upon seeing the emulator in action, but that's expected. Interesting videos, but we're still wary of its authenticity. So, until the final version is released, we'd treat this as a "potential" PSX emulator.

By the way, you have to brush up on your French to better appreciate the videos. From what we've gathered, the first video shows an Elite demo, an Amiga demo ported to PSX. If you look closely, you'd see a framerate close to 60. On the other hand, the second video shows a PSX homebrew game called Wargate. Nothing much to see but a spaceship. But that's ok, after all, it's just a proof of concept.
