You can enable cheats by creating a shortcut to GalCiv2.exe and use that to start the game.
1. Use Windows Explorer to find GalCiv2.exe, or right-click the game in Stardock Central and select Open Folder
2. Right click on GalCiv2.exe (not GC2Launch.exe) and choose create shortcut
3. Right click on the shortcut and choose properties
4. Click in the target field and hit end, then hit space followed by the word CHEAT (no switch marks necessary)
For example:
"C:\Program Files\Stardock\TotalGaming\GalCiv2\galciv2.exe" cheat
For Dark Avatar, the shortcut should be:
"C:\Program Files\Stardock\TotalGaming\GalCiv2\DarkAvatar\GC2DarkAvatar.exe" cheat
The cheats can then be enabled in game by pressing control and one of the key listed below. For example, pressing control and m at the same time will add 10,000 bc to the treasury. Some of these combinations, such as Ctrl+N, are not technically cheats and so do not require the procedure above to enable them.
Ctrl +
* A - Upgrades selected ship's quality, hp, and movement

Just get cash, reveal the map, get spies, spy the planets of the enemy until you get full ability to watch them. Maybe the only way to watch how they play.
