Sony has denied responsibility for the failure of three PlayStation 2 games to work with the console's most recent revision. It's the software's fault, the consumer electronics giant said.

The software in question comprises three titles - one of them from Konami - break when run on PlayStation 2s shipped after 8 December. At that point, Sony revised the console's hardware to support a bundled remote control for the machine's built-in DVD player, Bloomberg reports.

The three games, we understand, are: Idea Factory's Sky Surfer, Reiselied from Konami and T&E Soft's Golf Paradise.

For its part, Konami said it will replace older CDs with a new version that does run on the upgraded console.

This isn't the first time the PlayStation 2's DVD facility has caused trouble. Not long after the console made its Japanese debut last March, faulty Memory Card modules, apparently in conjunction with a glitch in Ridge Racer IV, zapped the DVD playback software stored on them. Sony later built DVD playback hardware into the console for its US and European launches. ®
