If you haven't already, I suggest you read Dane Kosaka's step by step guide to
scanning Kodachromes with Nikon scanners using Nikonscan software:
Most of what Dane recommends can be done with Vuescan as well as with Nikonscan.
Since the slides are faded, Vuescan's "restore color" filter might be worth
Generally, Digital ICE (or the Vuescan equivalent) does not work well with
Kodachrome. You can look forward to a lot of rubber stamping to get rid of the
dust and grunge.
I'm perplexed by the image size of your slides. 22mm square might be from a
Robot camera? But you imply the image is too wide to scan -- have you mixed up
your millimetres? Maybe these are slides on 127 (Vest Pocket) size film, with an
image about 38mm square? From a Baby Rollei, or from a Brownie Starflash?
