Emulators, cores, and the architecture behind preserving and playing classic games today.
How brightness-sensing and beam-timed light guns worked with CRT raster scanning, why flat panels break them, and how emulators map modern replacements.
Recover emulator saves by preserving originals, identifying the storage format, validating copies, and testing restoration in an isolated profile.
Eliminate emulator netplay desyncs by matching builds, content, firmware, saves, controller types, and deterministic settings before tuning latency.
Separate television zoom, frontend viewport, shader masks, core overscan, and intentional border pixels before changing retro-game geometry.
Diagnose regular emulator judder by measuring content and display rates, separating workload spikes, and configuring VSync or VRR without speed drift.
Diagnose missing RetroAchievements through account tokens, recognized game hashes, supported cores, Hardcore rules, connectivity, and session logs.
How source refresh rates, audio clocks, host displays, queues, and synchronization strategies create smooth motion—or periodic stutter and latency.
Create a privacy-aware game inventory with stable IDs, condition records, calibrated photographs, archival masters, provenance, backups, and valuations.
Build an FPGA retro system with documented hardware, trusted firmware and cores, lawful content, safe power/video, tested saves, and reversible updates.
Run an already-configured RetroAchievements Hardcore session with a clean reset boundary, native-save discipline, legal hotkeys, and auditable evidence.
