It looks like Sony's been reading our daily email missives, bemoaning the state of its PlayStation certified gaming selection. The message appears to be getting through, with several PSP titles getting spotted over at the Entertainment Software Rating Board with PlayStation certification. Ahead of any official fanfare, there's no big hitters here just yet, but titles like Syphon Filter: Dark Mirror and Daxter are likely to be more resonant with gamers than the pitiful offering we've seen so far from its PS Store app. Alongside Syphon Filter and Daxter, PS3 port Fl0w and Pinball Heroes were also spotted getting their contents okayed by the ESRB. Unsurprisingly, there's no detail here on release dates or technical requirements -- something that we reckon could be important, given the technical gap between the Xperia Play and the dual-cored innards of Sony's tablets. It's also worth noting that Pinball Heroes is already available on the Tablet P. Sorry Sony, but we'd still trade all of what's been leaked here for a portable version of the original Metal Gear Solid -- without hesitation.
