November 6, 2006 - Easily the most common question we get regarding PlayStation 3 backwards-compatibility, and possibly even PS3 overall, is whether or not we'll be able to play the Guitar Hero series on the PlayStation 3. Up until now there hasn't been any sort of official word of an adaptor for the PS3, but it seems that Radio Shack has the answer for us with part number 2600729.
Its "USB Adapter for PlayStation 2 Controller" (which many other manufacturers also make) is intended for using a Dual Shock 2 on a PC. Since the PS3 has a series of USB connectors, we went ahead and tried using a Dual Shock 2 on the system and lo and behold, it worked. The D-Pad and analog sticks can't be used at the same time, as you need to use the Analog On/Off button to switch between the two, but otherwise it seems to be 100% functional.
Our test system doesn't feature backwards compatibility, so we can't actually test Guitar Hero or its sequel on the system, but it certainly looks like everything should work fine on a retail unit. We'll have a final retail system in our hands very soon and will try this out once it's in the office and update this story accordingly. But for now, yes, it looks like Guitar Hero will work just fine, and we can all thank the rock gods for that.
