Trainers in Pokémon Emerald Rogue

Boss teams are generated when the fight starts, from a type, a set of slot budgets and a scoring script — there is no roster in the game to publish, and inventing one would be worse than saying so. What is exact is the level cap at each of the 14 bosses, and that is on the stage picker. How the generator works is written out under 'Bosses' in the reading notes. Everything the author did document — wild encounters, movesets, stats and TMs — is in the guide.
