I too noticed that several of the cheat options (in the 2.0 Trainer) stopped working part way into the game.
If you use Cheat Engine, here's how to find the Minerals, Energy, & Influence.
1. Setup Cheat Engine to scan the game.
2. Tell it New Scan and set it for unknown values.
3. Run the scan.
4. In the game, increase or decrease your desired resource and pause the game
5. In CE, tell it to look for values increased or decreased based on what you did.
6. Repeat steps 4 & 5 until you get the list down to 2k addresses or less.
7. Look through the list for a number that starts with the amount you have in the resource.
EX: You have 4,532 minerals. In CE, look for a number that starts with 4532. The number you find will be larger (3 more digits to the right).
8. Select that address and freeze it.
9. Set that address value to whatever you want, 5k for example.
10. Game changes to match the new value. Just remember, while the game displays 5k Minerals, CE will show 5000000.
Repeat the above steps for each resource you want to freeze / make unlimited.
