Switchless mod saturn board - main va sd usa?

Hi all,

Been away from modding consoles for a few years and now I've started again and was going through my stash of consoles last night.

That's when I found this saturn that I had started to switchless mod a few years ago. The only problem is I can't find any info on how to mod this revision moard!

The revision on the board is...

Saturn main va sd

Is there anyone here that knows how to switchless mod this version? I've done the switchless mod and region free bios mod on a lot of saturns, but this one has me stumped.

I'll include some pics(from the saturn wiki) of the board I'm going to be working on.



Any help would be much appreciated.

Thanks

Thanks for your reply Druid II

Think I've noticed my problem, I've not lifted pin 1 of IC20.

Will try it later and see how I get on...
