First PSP game to force firmware update via UMD game
Well we've all heared the rumors and announcements, but we didn't want to believe them. Now we have more proof that future games will force firmware upgrades. This indicates that it does not require an update to firmware version 1.51 or 1.52.

We just have to hope that forced firmware upgrades to 1.51 or 1.52 aren't in the near future. The US release of Coded Arms is has recently been delayed, and is now slated on the 15th of July.
