A binary is not an operating environment
A program assumes more than an instruction set: binary format, ABI, memory conventions, system services, threads and graphics interfaces all influence whether it can execute correctly.
Separate layers before implementing
Compatibility work becomes easier to reason about when the loader, symbol resolution, runtime services, platform APIs and rendering path are treated as distinct subsystems with explicit boundaries.
Verify assumptions, not only boot behavior
A successful startup is a useful signal but not evidence of correct execution. Calls, state transitions, memory lifetime, synchronization and graphics output need targeted checks.
Respect platform and distribution boundaries
Technical exploration should not be mistaken for authorization to distribute proprietary software or assets. Use lawful test material and clearly distinguish original work from third-party content.
Thoughtful engineering starts with accurate problem framing, clear constraints and repeatable experiments.
