UPDATED VERSION HERE https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2514089452

Here is how to make them
Use Notepad++ to edit multiple files at once using the find and replace in all open documents. Then quickly save the changes by closing Notepad++ and repeatedly pressing enter to save changes before closing.

1. Download the mod which you wish to ruin and 1 credit 1 second core

2. Navigate to the Empire at War workshop folder C:\Program Files (x86)\Steam\steamapps\workshop\content\32470

3. Open the folder for the mod which you wish to ruin. The name of the folder will be the steam worshop ID. For example, thrawns revenge would be 1125571106

4. Open the folder Data\XML\Units folder, there may also be more folders with upgrades, heroes, or other units which you will also need to open depending on the mod.

5. Copy those files into another folder with the same file structure which will act as your content folder. By same structure, I mean use the same folder names and put files into a folder with identical names to the source mod.

6. Open every XML file containing units, heroes, upgrades, buildings, and other construables, and do the following. (make sure that find and replace is set to Regular expression, and . matches newline is unchecked)

For 1 credit 1 second, change the following to 1

• Find: <Tactical_Build_Time_Seconds>.*</Tactical_Build_Time_Seconds>
  
• Replace: <Tactical_Build_Time_Seconds>1</Tactical_Build_Time_Seconds>
  
  
• Find: <Tactical_Build_Cost_Multiplayer>.*</Tactical_Build_Cost_Multiplayer>
  
• Replace: <Tactical_Build_Cost_Multiplayer>1</Tactical_Build_Cost_Multiplayer>
  
  
• Find: <Build_Cost_Credits>.*</Build_Cost_Credits>
  
• Replace: <Build_Cost_Credits>1</Build_Cost_Credits>
  
  
• Find: <Build_Time_Seconds>.*</Build_Time_Seconds>
  
• Replace: <Build_Time_Seconds>1</Build_Time_Seconds>
  
  
• Find: <Tactical_Build_Cost_Campaign>.*</Tactical_Build_Cost_Campaign>
  
• Replace: <Tactical_Build_Cost_Campaign>1</Tactical_Build_Cost_Campaign>

For infinite unit cap, do the following

• Find: <Population_Value>.*</Population_Value>
  
• Replace: <Population_Value>0</Population_Value>
  
  
• Find: <Space_Override_Population_Value>.*</Space_Override_Population_Value>
  
• Replace: <Space_Override_Population_Value>0</Space_Override_Population_Value>
