This was often traced to using an outdated version of chdman (e.g., CHD v4 versus v5).

Absolutely. By adopting in 2021, users halved their storage footprint, eliminated cue sheet errors, and simplified their emulation libraries. The format turned a messy folder of 50 files into a clean list of 20 CHDs. DuckStation’s support made the transition frictionless, and the performance impact on modern hardware was non-existent.
Manually converting hundreds of games one by one is tedious. The real power of chdman is its ability to handle batch conversions, which can be achieved with a simple script.
