Show HN: Rat Race (After Dark, 1994), ported from 68k assembly to TypeScript
Ported to TypeScript from Motorola 68k assembly! All the rats' behaviors are true to spec: Their distractions (sniffing, turning around, grooming, stopping) are all frame accurate and occur in the same ratios as the original. The artwork and animation speeds were extracted from the old bitmaps and jump instructions and are (as close as I can get) to being frame accurate. Enhancements: I ran tens of thousands of simulations and fixed a few unfair advantages rats had if they were in the outside la

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.
