You can perform a hex edit (using an editor available online) to provide your Global Treasury with an influx of cash. To do so, complete the following process.

Open a *.SAV game file in the hex editor
Go to block: 7414
Type in 1388 (which should appear as 13 88 in the editor)
Save the file
Reload the file in-game and look for your increase on the "Planets" screen

Additional codes are available that provide additional money, including a hex value of 5F5E1 that will yield $1,072,735.
