// the correct GameSettings for a given game variant.
//
// The first listed variant is assumed to be the 'default' variant -- i.e. the
// variant that gets used when no explicit variant code has been specified.
//
// Note #1: Only set 'platform' to a value different from UNK if that game
// variant really *only* exists for that given platform. In all other cases,
// the correct platform will be determined via the MD5 table or derived from
// the filename.
//
// Note #2: Make sure that all variants for a given gameid are in sequence with
// no gaps. Some code may rely on this and stop searching the table early as
// soon as the gameid changes.
//
// Note #3: Use 0 (zero) for the variant field *if and only if* the game has
// only a single unique variant. This is used to help the detector quickly
// decide whether it has to worry about distinguishing multiple variants or not.
