5.00 M33-5
Changes includes those from subsequent patches:
- A setting has been added to recovery, that, when enabled it may increase memory stick reading speed. (only on the psp, not in the pc).
- By default it is disabled. If you installed 3.71 fatmsmod, do not use this setting, as its performance with 3.71 driver has not been tested. Instead, reinstall 5.00 m33-4 using dc8 and update to 5.00 m33-5
