The SNES is only physical. Stock system and or stock carts, a Super Famicom cartridge will NOT fit into an American SNES unless you cut out the tabs inside the cart slot or the slots on the back of the cartridge. I bet the store that sold the imports was cutting slots into the back of the carts.
Not quite. Don't forget the European Super NES, which has a physical lockout on North American cartridges, but an electronic lockout as well due to the shape of the cartridges being the same as Super Famicom cartridges. European Super NES cartridges and consoles use a different lockout chip than any North American Super NES or Super Famicom cartridge(both the North American Super NES and the Super Famicom share the exact same lockout chip). This prevents all NTSC games from working in a European Super NES unless you A) disable the lockout chip(in turn, causing games with the SA-1 co-processor which can detect the presence of a lockout chip not to work), B) replace the PAL lockout chip with an NTSC lockout chip or C) rig up both an NTSC and a PAL lockout chip and activate whichever one is needed. You would also need to widen the cartridge slot so North American Super NES games can fit.
The difference in lockout chips also prevents European Super NES games from running on any NTSC Super NES. You would need to once again either disable the existing NTSC lockout chip, wire up both the NTSC and PAL lockout chips(I'm not even sure this would work) or replace the lockout chip entirely, and if you have a North American Super NES, break the tabs in the cartridge slot.
