But in case that you ask for a tools so you can hex edit the game. download HxD (Google it). Install it and youre done. Also if you were going to edit some of the encrypted files like edat , selfs, sdat. You need to decrypt them first. If the game is builded on some other game SDK like Criware, you might need to do a reversing their files on your own or just ask someone who can do that job for you.
