I dunno... I followed everything.
Open game, play for a while, save, close game, open texteditor, find file and modify things in the same file you opened, then i saved the modifications, then i loaded the save file (not auto)... but Too bad nothing actually happened. The money remained just like it was before.
Can you explain better if you can? Well you didn't explain things and well... I don't like the "you can do it yourself".
Well whatever. The game is outdated, but it still works...
Still Great.
