Well they are still labelled PPU1 and PPU2. Also I have had confirmation that at least some models with SHVC plug in sound module can be modded no problem. I've also read the voltages while running. 5V is getting to the correct connector on the switch via the 2.2k Ohm resistor, but when the switch i...

Well, I redid the mod completely. At the same time I modded to other PAL Sneses. Both the PAL snes' now swap 50/60Hz perfectly, and still the jap snes will not shift from 60Hz. At all. Its rock solid. I used new switches, a different resistor (in fact one pulled from a another working mode). Bleeped...

Ok Thanks.

Not quite clear where I've gone wrong then, as the pins are getting 5v or ground depending on the switch as expected.

Same pins I take it? It seems setting the pins (30 and 24) to 5v or 0V has no effect on the ouput. Weird. I've modded loads of PAL snes', but not seen this...

Can a Jap Super Famicom be modded to 50Hz? I have just modded a JAP and UK Snes, and the UK one works fine, swapping from 50Hz to 60Hz, but the Jap one does nothing - remains on 60Hz all the time. I've tested out my wiring - all continuity from switch to ppu pins is fine. Just trying to do a sanity ...
