Art from our forum has released X-Flash v1 for PSP. X-Flash is a firmware tweaking & modding tool. It can delete the gameboot movie, remove the wave lines in the background like FlashMod, and copy font into the firmware. However, this release doesn't have the "restore to default" option, though Art said this build is very stable and well tested. Art will continue to polish the interface of the program like the XMB interface. You will be able to select fonts, sounds, version numbers and etc.
