Definition:
A downgrader is a piece of specially-developed homebrew software that returns a PSP's firmware to an earlier version.
As of this writing (summer 2009), there are downgraders available for firmware up to 5.03. Different firmware versions (and in the case of the TA-082 motherboard, different motherboard versions) require different downgrade software. A downgrader for firmware 5.5 is in development.
Downgrading a PSP's firmware to version 1.50 allows all homebrew programs to run on the system. Only some homebrew will work on versions higher than 1.50.
Pronunciation: DOWN-grayd-ur
Also Known As: downdater
Common Misspellings: downgarder

A downgrader is in development to change version 2.5 and 2.6 firmware PSPs to version 1.50 firmware.
