Learning Empathy From Pokemon Blue
summary
A concrete, reproducible exploit: a mismatch between which subtile the game checks (bottom‑right for encounter chance but bottom‑left for which monster) plus reused memory for trainer names and the grass encounter table means a crafted name or the “old man” tutorial copies data into grass encounter table at D887, producing 128 rare candies (and with the old man method, infinite dupes). Analysis uses disassembly and Ruby-translated pseudocode to show Z80 limits (only four general registers, 207‑byte stack) and that MissingNo is actually 39 internal slots, not a single monster.
