Following the anticipated release of PSP custom firmware 3.80 M33 and the rather quick bug fix update, M33 have released a 1.50 Addon for FAT PSPs running 3.80 M33 only.
This release does not come with any instructions, but thanks to MrTuto_Alek we have instructions on how to install this 1.50 Addon for you:
Instructions.
- Copy the files in the release to a directory called UPDATE
- Move the UPDATE directory to /PSP/GAME380/UPDATE.
- Get sony 1.50 update and copy it to the root with name “150.PBP”
- Run the program and done.
As we reported earlier, 3.80 M33 includes a new feature to update the firmware directly via Network Update however this will not work for this 1.50 Addon as it is an optional addon (and only for FAT PSPs).
Finally, please note that 3.80 M33 must be installed before installing this addon.
