So after modifying one of my SNES units to play games from all regions, one of the short comings was that I could only play Japanese and PAL carts due to them being the same physical shape.
So i had a second unit which i decided to take one step further, so i fitted another SuperCIC and this time went about modifying the cart slot. I managed to source a slot cover from a US machine and went about making the bugger fit. After a lot of cutting it fitted. It looks quite good if i do say so myself and i tried to keep it original looking as possible.
Effectively this is a universal SNES
