Operating systems, infrastructure, emulation, and technical history.
An engineering view of emulator audio clocks, sample generation, resampling, buffer control, drift, latency, time-stretching, and deterministic testing.
A preservation-focused guide to MAME CHD hunks, codecs, hashes, parent-child images, metadata, creation, verification, extraction, and version control.
A layer-by-layer color diagnostic for emulators covering source revision, palette RAM, pixel formats, endianness, color management, shaders, and captures.
A non-destructive RTC troubleshooting workflow covering save provenance, host time, core format, latch and halt state, state conflicts, migration, and proof.
A practical distinction between HLE and LLE, firmware replacement, timing and side effects, legal provenance, hybrid systems, and compatibility testing.
A lawful optical-media preservation workflow covering drive choice, disc condition, raw sectors, audio, subchannels, retries, hashes, metadata, and repeat reads.
A provenance-first ROM audit workflow using hashes and DAT metadata, with immutable originals, header rules, set semantics, tool logs, and exception review.
A hardware-grounded guide to cartridge address decoding, PRG and graphics banks, mapper registers, mirroring, IRQs, save memory, and emulator tests.
How cartridge SRAM, flash, EEPROM, and RTC registers persist; how emulators serialize them; and why wall-clock policy, atomic writes, and testing matter.
How scanline sprite evaluation, object limits, priority, overflow quirks, flicker strategies, and emulator options shape authentic retro-console graphics.
