Was gonna do a 60Hz mod on my SMS1, I found the right jumper and cut the PAL trace.

When I connect the NTSC jumper it jumps to 60Hz and when I disconnect it it goes back to 50Hz and seemed to work fine with the PAL trace still cut.

I only tried using an RGB cable. Right now both PAL and NTSC are disconnected and it works in 50Hz PAL like that using the RGB cable.

My question is (as i put it away before i thought of it) is, will it also work using RF or AV as it is ? (with both PAL and NTSC not jumpered)

No, it will only work with an rgb signal. You are not changing between a pal and ntsc encoding, you are changing the frequency.

So now being neither set as pal or ntsc what will it do if I try an RF connection or AV ?

Well, if it's running 50hz, then it's still a valid pal signal.

Edit: I'm writing nonsense, I think :) The sms is fine with composite at 60hz.
