This hack is always enabled when using the Mod Launcher.
This is an advanced hack that can only be required by other hacks.
This hack allows other hacks to store custom save data on the end of the save file.
It also always stores extra reward related information on the end of save files. This information is harmless and does not affect save files when they're used in an unmodded copy of the game (though the data will be lost if they're saved over without the hack enabled).
Version History
Version 1.27
Now makes the game mark wager races as completed in the save file, regardless of what kind of mission they are.
Ordinarily, the base game only stores a best time upon completing a standard wager race.
This change has no impact on vanilla gameplay but enables mods to check if these missions have been completed even if they are not actually a wager race, such as Donut Mod's Taxi Missions.
Version 1.23
Made it so this hack can no longer be required by mods.
