You just need a hex editor (I use HxD) and a few minutes.
Start a new game and make sure you turn on unlock everything.
Save the game and quit.
Now go to %appdata%/locallow/eggcode/Mad Games Tycoon and load
the savegame into HxD. Your savegame is numbered 1 less than the
slot it uses.
Now search for this hex value 7B 7E 05 6D 6F 6E 65 79 0A 00 00 00 07
Change the next 4 digits to whatever you choose
FF is always a good
max value.
Save the file and load up your save in MGT, and play creative with
more money than you need.
