saturn region mod

[cosine]

Hullo, hew person here

For a while now, I've had a saturn which I jumpered to run japanese games (since I game my euro games away, but not the console), but it's started to look tired and scratched up, so I went onto ebay, and picked up a euro mark1 saturn (the one with the CD access LED).
Since this is the place I got the region jumper info, I came back, and found the switchless mod, and thought "great, no drilling for me!"
However, I opened up this mark1 saturn and came across a couple of surprises (to me). Firstly, this thing seems to have the same PCB as the HiSaturn Navi, with a seperate board the joypad connectors, and secondly there is no resistors soldered to specify the region, from JP6 to 13. As a test, I dropped in a japanese game, and sure enough, it refused to start with the usual error message.

So after all that, I suppose my questions are:
were "mark1" saturns known to use the HiSaturn PCBs? and since there's no resistors where I excepted them to be, where can it be possibly pulling the region info from?

Thanks

If there are no resistors you'll probably find that there are traces on the PCB connecting the two pads.  Cut them with a sharp knife (be careful!).

Yes, the board is well known.  I should prolly update the page...

doh! so there is. The thought never even entered my head.

Thanks
