Saturn modification diagrams?

Hello,

I am looking for the diagrams and CLEAR instructions to modify a Japanese Saturn (Model 2 - round buttons) to play US games on it.

I looked online but could not find a clear explanation on how to do it (and there seems to be like 4 or 5 ways to do it differently).

Anyone has clear Diagrams and intructions on how to do that modif (Ideally internaly, no switch)?

Thanks

From what I know, you definitely need a switch or at least a jumper edge (which is nothing different but you can put it inside).

I did it this way:

All diagrams show the same thing, the only difference is the look of the jumpers and where they are located. I did this about 1 year ago but I think I used the gamesx schematics:

here is the modchip install , not sure if what you want is similar?

The problem is that there are so many different models of Saturn motherboard out there that you'd need a dozen different diagrams for a page like that.

The concept is easy, though, and can be summed up in one sentence:

Have jumpers 7 and 10 closed for US mode, and jumpers 6 and 11 closed in Japanese mode.

That's all you need to know. Think about it for 5 minutes or so, and you should be able to figure out how to do the mod.
