(adsbygoogle = window.adsbygoogle || []).push({}); Some of the PKG files I get from PSNSTUFF come compatible with a firmware lower than 4.20. I am on 4.80, is there a way I can patch/fix these files myself so that they work on my firmware? I am running Rebug 4.80.1.

Maybe using psnpatch or editing the param.sfo?

I've tried PSNPatch to no avail, will try again now. Not sure what I'd be doing if I edited the param.sfo...

change the firmware version in param

Is there a tool, or application I can use to do this?
