has released a new
version of his PSP CFW today, specifically v3.73 HX-1
Consisting entirely of his own IPL, the updater is compatible with both PSP/PSP Slim and will check automatically upon launching it.

Changes include all of the changes and features in 3.73, along with correcting a VSHCTRL bug (corrupt icons in VSH 'Game'), and as a safeguard the updater will backup the current config files in case any CFW recovery conflicts occur.
Note: You must be running an existing PSP Custom Firmware prior to installation.
