I recently ran a 126 roll from 1983 and got pictures. Not great, but they did come out.
I put a used flash cube on top of my K-104 to force the slower shutter speed and shot in daylight. Then I over developed the film by 30 seconds. DIY C-41 is fun.
I now have 4 126 carts reloaded with fresh Portra 160nc, waiting to be used.
I still can find color 110 film at camera swaps but it is getting scarce. New 110 and 126 would be amazing.
