I stumbled across a forum post a while back detailing a switchless mod for the SNES.
A forum member Ikari_01 has reverse engineered the CIC lockout chip and created his own and it is stunning.
I followed these diagrams and burned the latest .HEX from Ikari_01 to a PIC16F630.
The mod works very well so far, am waiting for a few more games to get here and a dual LED.
Ive got some different games coming and will update this post when I’ve finished testing.
UPDATE: I’ve finished testing this mod using 3 of the cheapest games that eBay had to offer, one from each region.
Ive also now hacked away a little at the casing of the SNES so US cartridges will fit in too. Its VERY rough but functional.
