There was STOS squasher which was an extension. Though it compressed mbk banks.
AFAIK, there was 2 versions of STOS FIX, one pumped all of the tables for all tos versions (14 I think?) the other one allowed you to just patch 4 of them. I think the prg files only had space for 4 tables, something like tos1.0, 1.2,1.4,1.6..
Not really sure what your exact problem is but stosfix should be able to defualt the tables back to ST ones. Or patch the prg to all 14 tos tables. It has been years since I used it so can't exactly remember.
