In the first case you also have guess the compresson algorithm.
It will work if you decrypt the file, but it is easier to use the R4DS cheat editor: http://www.r4ds.cn/download/Cheat_code_editor.html
It's a clone card of the R4, but it should be able to work with the same cheat file, otherwise it uses a decrypted cheat file, which you can decrypt using a file called r4crypt
You can use C++ program to decrypt 3 digit number
