Page 1 of I need help with my Cyberhome 512!

I am trying to convert this player to multi-region. I have no problems getting to the hidden setup page but that`s as far as I can go!
I am finding it difficult to alter the c-code setting.
Any advice would be appreciated.

u might need to load in an older version of the firmware as all new models dont have the hack see http://www.cyberhome-help.de/ for details
