Sega Saturn PAL VA13 50/60hz switch mod - how-to - HELP

[res]

Hi folks,
New user so sorry if i break any posting norms... anyhow,
I just opened my pal Saturn to find that its a va13 board. I want to mod it with a 50/60hz switch since I use a action replay cart to play imports and save/RAM. 


How to mod Sega Saturn VA13 PAL 50/60hz Switch: 

  I assume you have a region free console with the ram cartridge or other methods, and only use RGB .
  I did this mod on my own console. I hope this helps other people. 


You just need to remove the component connecting jp2 to the pad to the right and connect your 3 prong switch accordingly to the 3 pads I talk about. VA13 models are the easiest to mod, after the models with the pads by the battery.

Red and Black, jp2 jp1, are the switch side prongs. the grey/yellow is connected to the middle prong.

VA13 PAL uses the newer PLL chip which is not connected to JP1/2, so I think you can get away without cutting any traces. Composite and S-Video output might not display color, but I'm honestly not at all sure because I only use RGB which will be unaffected and work fine regardless. If you are adamant about having composite video you can still cut whatever trace leads to pin 7 of the video encoder, and then ground it separately so it always outputs PAL (or PAL60).

OK. So what do i have to solder then? same spots as va9, just no trace cutting? dont need to remove any components like the resistor at jp2?

I don't know what guide you are referring to, but yeah, you should only need to remove the jumper in jp1/2 and replace it with your switch.

OK, just to be sure, this is how id do a switch mod va9 vs a va13, just remove the jp2 jumper in va13 (orange) and connect to the switch according to the colours? zyrobs

I think the bottom picture should work, yeah.
