I just figured out...

In Hardware

That the only regional lockouts on the SNES and N64 are physical blocks on the cartridge slot. I assumed that because the NES had a chip, the newer systems would too.

I can't wait for my gamebits to get here so I can open the systems up and remove them.

It also means if anyone needs a region-free N64 or SNES, I'll have a nearly limitless supply.

Are there two diffrent sized bits that Nintendo uses? I thought I read some place that they use 5mm on the consoles and 3mm on the games, is this true?

Thanks.

Not sure about SNES (don't have the system or any games), but I do know that the N64 games need a 3.8mm and the console uses a 4.5mm.

the N64 has a block of plastic on the system just open 'er up and unscrew what holds it on, the SNES has to Blocks of plastic on where u put the cartridge in, just look there and where the back of the cart would be theres twon things sticking out, just cut them out, and there you go, i got half way with mine, i used a steak knife , but it didnt work too great, if i took the thing apart it would of been alot easiar.

atleast this is what im Quite sure about,

Youd be better off having a lighter or propane torch, heating a razorblade, and just slicing through them easily and neatly, dude.
