FAQ – GH1 Ptool Firmware Development
dude named tester13 has started experimenting with the GH1 firmware and is making a patching tool available. Nothing I’d risk trying right now, but could eventually fix problems / add features like: pulldown-free 24p, higher bitrate recording, more options for MJPEG recording, maybe even live video out. If it works the GH1 will suddenly be competitive with the Canon VSLRs again.
