So it is that straightforward for a proof of concept (downgrade to an old version of Zig compatible with the project, patch an undefined variable bug the author introduced yesterday, s/32/64, add 4 bytes to main.zig->Header and its accesses). Doing so makes the program slower though which might be a non-starter for a performance focused project. Plus you'd need a little more work to properly handle large archives on 32-bit and smaller systems (at least those which support >4GB files).
