I just spent the evening modding my PAL SNES with two switches for 60Hz switch and lockout chip switch.
I can confirm mod works, I get 60Hz screen (full size) and lockout is disabled because Final Fight 3 and Donkey Kong Country runs without problems (both USA releases).
But I can not turn off 60Hz to go back to 50Hz, in both positions I get 60Hz, the same with lockout chip. Final Fight 3 and Donkey Kong Country runs fine with lockout switch switch in either position.
The lockout mod is the usual pin 4 lifted on the lockout chip, attached with Kynar wire to middle pin of switch, left pin get 5v right pin get ground.
The 50/60Hz mod is the one where pin 30 and pin 24 is lifted and connected to middle pin on switch, 5v on left (throgh resistor) and ground on right.
Just like: http://www.gamesx.com/importmod/snes5060.htm and http://www.gamesx.com/importmod/sneslockout.htm
(I got 5v from "O" and Ground from "G"). Anyone knows the problem?! :crying:
