Yes, that's what i meant by except the NA snes, you can use a bypass region lock adapter, but I don't recall the other region Snes to work with it.
(Should have presiced more what I meant but too lazy XD)
Now we're kind of going offtopic, but actually every Nintendo system NES to N64 had region-locks, but this was determined by NTSC/PAL. So a PAL game (which would be European or Australian) wouldn't work in an NTSC (Japanese or American) system.
This was an electrical lockout (well, not in the case of the NES... the game would just run faster or slower depending on the region due to a different clock speed. They would also only play if you disabled the 10NES lockout).
Now, Nintendo also made two regions within NTSC. Asia and the Americas. These locks were physical. I.e. either the pin configuration was different (NES/Famicom) or there were plastic nubs preventing other region games from playing (SNES/N64). In the case of the SNES or N64 one could simply cut out the nubs or file them down to make out-of-region games fit in the cartridge slot and play. All those so called "adapters" really do is carry the pins directly without re-arranging them or anything because it's not necessary.
In the case of the NES/Famicom you would need an adapter to re-arrange the pins to play said game. You would also have to disable the 10NES lockout chip in the case of Famicom games on the NES because the 10NES would keep resetting the system as the famicom cartridges lack the second 10NES chip.
If you have no idea what a "10NES" is go

ONTOPIC: Region lockout < my cat. I want to play my Japanese copy of Tobidase: Doubutsu no Mori on my American 3DS XL as opposed to my small and tiny Japanese Cobalt Blue 3DS
So I hope this hack gets rid of it!
(If you couldn't tell, my "ontopic" portion of this post is pretty much just rehashing 50 pages of this thread... the other 19 being useful posts...)
