Is it enough by changing the values of Hfuse and Lfuse in your given sketch according to the specs of Atmega8? Thanks for the project.

Thanks for the project, it's like a cushion against the floor for many of us. I happened to get better results with an N-mosfet 2n7000 instead of the NPN transistor, as it was not being able to fully pull the RST pin to ground, but to a mere 7.3V or so. Hi!

If you try it, please report your findings in the forums. The ATmega64 supports HVPP, so there’s a good chance that it will work with the shield.
