I know that C-41 process films could be developed in the old C-22 process, but the colour balance was way out (I know this thanks to a careless processor, way back when Vericolor was first introduced). I'd guess that C-22 material could be developed in C-41 with similar results.(posted 8825 days ago)The old C-22 process chemicals aren't available any longer. I doubt if you'd even get the raw chemicals to make them up. Old unmade up kits lying about on dusty shelves are likely to be useless by now too.
I'd recommend shooting the rest of the roll, and using it as clip test material. Give it a try in C-41 chemicals and see if it's printable. As a last resort, the film could be souped as B&W only.
