Pages tagged koei — KOEI’s 8-bit strategy games (Nobunaga’s Ambition, Romance of the Three Kingdoms, Genghis Khan) as decompilation + game-design specimens.

• KOEI AI & combat evolution — a five-decompiler study
• The Dead-Verb Test — does KOEI learn?
• The Hollow Opponent — NA1’s AI decoded
• NA1 crucible
• L’Empereur — the two-tier turn (NES→SNES design hinge)
• 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
• Nobunaga’s Ambition (SNES) — the VM exception, compiled native — the one KOEI SNES port with no bytecode VM (native 65C816); first HiROM title; hypothesis: NA1 = oldest game, predates the VM
• 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
