Every trainer battle and wild encounter in Pokémon LeafGreen, ordered by when you can reach it and solved with the Game Boy Advance's own damage formula — plus a recommended party for each stretch of the game, with PP and HP counted across it.
Built from the pokefirered decompilation — base stats, movesets, trainer rosters, encounter tables, healing spots and the damage formula are read from the game's own source, not from a wiki.
