On Windows your save game file for Gomo is located in C:\Users\<username>\AppData\Roaming\Gomo\Local Store\saves.dat



To edit make a backup copy and open with any text editor. The data is formatted with lable/value pairs separated by a "=", which are themselves separated from each other by "&" characters (ex: "a=1&b=0&c=1"). The relevant variables for us are "A", "B", and "CG", which are sequential and somewhat close to the beginning. If you have yet to unlock any it will look like: "A=0&B=0&CG=0". Change the "0"s to "1"s so that it looks like: "A=1&B=1&CG=1" to unlock all bonus mini-games.

Save the file and open Gomo, they should now be unlocked
