Worth noting that, especially for currentCheckPointID, the numbers in this guide are BINARY numbers, while Regedit may default to showing the keys in HEXADECIMAL. Make sure you enter them in the right format, otherwise you may get unexpected results (For example, if you completed the game and see currentCheckPointID = 24, that's a good clue that you're looking at the Hexadecimal numbers, since 24 Hex = 36 Dec.)
