I have done the simple AV mod for Atari 2600 (6 switcher, 4 switcher & JNR) as well as the 7800. This was done by the simple transistor + 2 resistor trick.
While it isn't bad, I am keen to know if there is a better way that suits PAL consoles. I know about Longhorn's mod board but I believe that is NTSC only.
Does anybody know of the equivalent of Longhorn's mod BUT for PAL consoles?
