    You’re quick admin, I sent it to you like a minute ago! :) btw, I can “confirm”, that it works well for GF1 as well.

      Thanks again! It was casual, because I was going to bed now! :)

        NP, I was so happy about it that I needed to share :) Have a good night then, I still have a few hours left here in central Europe :)

  • I have been trying to find out what PTool can do for a G1 exactly – with little success. Any pointers? Thx !

    I hope the G3 hack will be also available. As prices are much lower in US I keep thinking about buying the G3 from North-America…

  • good news, but the only thing that will put a smile on my face is a patch to make high bitrate audio recording playble in camera :\

    Tested on my previously unhackable GH1 1.34 (aug. 2010) and it works! Thank you, Vitaly!

  • Mr. Reeee

    Mac OS X or Windows?

  • Hey Admin! I dont want to hear about the the big old big clunky Gh2! I want to hear about the m43 sensored- “mini-pen”! :) It would make my photography reach new hights..

  • Has anyone hacked a GF1? It kinda worries me the “Untested for gf1” message nex to the “New body” patch…

      It is a hack, not a product with any warranty. If you are worried then educate yourself on the sites refered above – there is plenty of information. If you are still worried – don’t do it. If something goes wrong you have only yourself to blame.

      • Lflex, i understand perfectly it is a hack, thanks for your “clarification”. All I wanted to know is if someone had tested in on a GF1, nothing else. None of the other hacks have the “untested” label, that’s what worried me.

      Didn’t you read the first post here…ehm my post?

      • Cool, didn’t notice your post, thanks for sharing!!!
