// This is the REAL unlock mechanism: the game obtains the GDK interfaces

// this export and returns the REAL object with the license slots overwritten
// with "owned" answers (magic 0x539 / 0x1337).

// Installs the detour on xgameruntime's QueryApiImpl. Returns true if the

// schedules a retry in the background.
