I've been decompiling DOS games recently with help from the $20 subscription. The one compiled by the Watcom compiler took like two weeks, with 2/141 functions still not matching. The one compiled by Microsoft C reached a match in two days more or less.

I think this points in two directions - first that $200 is really unnecessary for this domain.

Second, that with more experience we might be able to write a non-AI matching decompiler and then naming and simplifying could be done by people/AI. While I appreciate the hobby part of it, I think automated tools are the way to really make it reach everything with far less dependency on pockets. The benefit to preservation would be incredible.
