New user-mode exploit found by coder jeerum with the help of N00b81 initially on the European version of the game Carol Vorderman's Sudoku in both UMD that PSN version, but also confirmed the U.S. version. At the moment it is a simple Hello world and have not been played a sufficient number of tests to verify its compatibility with the various firmwares. However, it is guaranteed to work on FW up to 5.50. This greatly reduces the utility, but the coder we have repeatedly surprised.
