9g TA95v1 PSP 3ks can be converted to a 4g, though 9g TA95v2 PSP3ks have had issues with downgrading back to 6.20 a 2nd time.
PSPident 0.75 is more recent
And Pro-B10 is out-of-date. Pro-C fix 3 is the most recent.

Is PRO-C official, or is it now opensource and those builds are no longer by the original Pro team?
