SAturn Region Mod Switch problem...

[retroborg]

So, I tried this region mod method:
www.mmmonkey.co.uk/sega-saturn-country-mod-3/

But it did not work!
I'm pretty sure I followed everything by the book as described in the link, but the console refuses to switch between the 3 regions, some times it will switch rendomly.

I could not find a motorolla Hex invertor, but only an equevelant SN74LS04N of a different brand.
So is the hex inverter actually needed and can anybody verify that this modding method actually works?! Before I mess up my Saturn?!

Thanks in advance

Those little things are so damn unreliable.

Better to install a region free bios.

So, is there anywhere I could get a reliable pre-programmed Region Free BIOS.
I searched ebay, but didn't find anything.
