And along with the excellent success the PSP has gotten, there also has to be a degree of headaches for Sony due to the enthusiasm of thousands of hackers worldwide who eagerly awaited the console's launch. As a result it is possible to run homebrew apps on the PSP under firmware versions 1.00 or 1.50. This makes it possible to play games that were not made for the console as well as various other tasks such as launching some PSP games from MemoryStick.
PS2NFO is reporting that there is a notice accompanying the PSP device which instructs users to insert the Demo disc for the latest system updates. This means that the European PSPs use firmware version 1.52. To anyone hoping to run homebrew on their PSP eventually, updating to the recent 2.00 is not recommended.
