Japan's official PlayStation site has just updated with a new downloadable that those who have a sweet tooth for custom themes for the PSP may want to hear about. It's an official release of Sony's very own theme maker for handhelds running on their official firmware.

While details are still sketchy at this point (it's all in Japanese), a quick scan of this new application's PDF manual reveals some interesting details. For example, we've spotted screenshots for what appears to be a custom icon editor (complete with step-by-step instructions). The app also carries its own theme converters, although once again, we can't verify this until we can pick up a more proper translation.

Guys interested in downloading a copy of this new tool can access it via Sony Japan's official site by clicking the Read link below. We'll let you know in case we hear news of a North American release for Sony's official Theme maker for the PSP. In the meantime, we'd really appreciate it if the more Nihonggo-literate readers could drop by and offer translations. We're sure the rest of the PSP community will be thankful as well.

We extend our thanks to Hatter for informing us of this new release.
