ZodTTD has made good on a promise to release their psx4iphone application to the public just a handful of days after announcing the project, meaning that the iPhone could very well end up taking a slot beside the PSP as a premier destination for portable PlayStation gaming. We're still not entirely convinced that the transition from PlayStation controller to touchscreen is going to be an easy one, though we're pretty sure hardcore gamers have overcome even greater obstacles in the past in the name of emulation. The package is being billed as a 0.1 release, meaning that it may not be the most solid build in the world -- but then again, it's not like you're getting your PlayStation jollies from Sony Ericsson any time soon, right?
