I've never been too interested in SNES / SF games so I did a little reading on region protection on those. It's based on the frequency of the console, so there is no US/JP compatibility problem as long as you use a cartridge extension to bypass the shape of the game cartridge.MachineAres 1CC wrote:As far as I know, EU and JP have the exact same cartridge shape, and the cartridge shape is the only thing that prevents you from using the US carts in EU/JP systems and vice versa, there's no actual coded region locking in the ROMs of the games. The only issue you might have is that if you're using an original European SNES to play it, they are coded for PAL video output, so the US and JP versions likely won't run correctly on a CRT TV since they're coded for NTSC. If you're using a Retron or other clone system that has HDMI output, you shouldn't have this issue, since it converts the video signal anywayplasticxo wrote:Edit : there seems to be 2 versions. One for the US market and one for the EU market. The shape of the cartridge is different.
But it is still not clear if the EU version will play on a Super Famicom...
Over US/EU or JP/EU compatibility, it's not the shape indeed, but the frequency that sometimes acts as a region protection. It's not the same on all games (some check at start up only, others after levels or game over screen too...).
I suppose retro-bit only changes the cartridge shape for its US and EU market, and the games are not region coded... But I can't find the answer and I asked retro-bit directly. But no answers until now...
