snes

Super Nintendo (SNES / Super Famicom) hardware and reverse-engineering — 65C816, LoROM/HiROM, PPU modes, SPC700.

• Breaking Down an SNES Cart — the teardown method — read the header, detect the mapping, lay the memory map, peel the subsystems; the architecture break vs. the NES 6502 work
• SNES teardown — snes-decompiler — process-table pointer for the target-agnostic SNES teardown substrate (verified header/mapper tools)
• KOEI’s portable VM (SNES ROTK2 reversal) — first KOEI SNES title reversed; byte-for-byte portable bytecode VM, faithful port + facelift (NES↔SNES comparison)
• Gemfire (SNES) fully decompiled
• The one that isn’t a VM — Nobunaga’s Ambition (SNES) compiled native — first HiROM KOEI SNES title; the exception that compiled straight to native 65C816 (no bytecode VM); drove a native 65816→C decompiler
• NA1 NES↔SNES — grading two blind reverse-engineerings — SNES-derived vs NES-derived, all 5 sections converge (record bytes, Grow formula, event cadence, weakest-neighbour AI, 8-stat combat table); create-then-check method
• Arithmetic as a Purchase — Sixty Years of Paying for Multiply — the SNES multiplier as a memory-mapped coprocessor, and the DSP-1 / Super FX cartridge chips as the Atari math box reborn — arithmetic priced per game
• Game Annotation Series — System-level deep-reads of classic game source — used as a stress test for LLM interpretation of
• Gemfire (SNES) — The second KOEI SNES title reversed — and the pass that exposed the trampoline bug in
• KOEI tools — the shared engine toolchain — Tools node, not a title index. One studio, one bytecode-VM engine lineage, two consoles.
• ROTK2 — Sangokushi II (SNES) — The first KOEI SNES title reversed, and the title that proved the portable VM from both sides.
• SNES system tools — snes-decompiler — The target-agnostic substrate for taking apart any SNES cart: 65C816, LoROM/HiROM detection,
