gen2recomp: recreating Pokémon games from cartridge data

gen2recomp recreates Pokémon Gold, Silver and Crystal in LÖVE2D with a handwritten Lua engine and Generation II script VM. Its importer checks a player-supplied ROM and decodes game tables, text and graphics into a private cache. The same launcher also offers early support for selected Generation III through V games.
