Show HN: Reversing Wing Commander to find the entity table in 64k to add co-op
I've always wanted to play Wing Commander with friends, so we could fly the story missions together. In 2015, I hypothesized that the full game state fit in the data segment (only 64k), and I could do small position and orientation experiments with vbindiff to discover how the memory was organized. Some fun findings: the camera was in entity index 0x3D (a "3D" joke?). My brother, Patrick, figured out Borland's overlay loader crashed the game until we made our stub look like a real stac

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
