The Game rules guide explains this folder.

The game object: the rules of the party and its world. Units and their stats, a new game, items and inventories, Psynergy and levels, the game flags, enemy units and the party's counters, element levels and classes, battle arithmetic and the Djinn.

game_internal.h holds what every part shares (its includes and one inline helper); the code is in the files under game/, included here in the order it has in the ROM. Camelot's own files are not recoverable: the ROM shows one object, and these parts are ours, cut where one family ends and the next begins. Its tables are the .tsv files in this folder, built by the .s files beside them; README.md gives the words and prefixes. Where to start:
