• The pre-built mod contains every possible setting enabled, so if you want to customize the experience, it is advised to use the builder application.
  
• Although I thoroughly test every change, it is more likely for bugs to occur in the development builds.

IMPORTANT: If you've installed any mods from this guide before, then proceed to the %game_root%/mods and remove everything that starts with PSPSX prefix.

1. At launch, the application will try to detect your PowerSlave Exhumed installation directory.
   
   • If that's the case, you can just skip to the next step.
     
   • If you don't see anything in the top text fields (Game Directory and Output Directory), or paths are incorrect, or you just want to place the mod somewhere else:
     
     1. Press the ... button next to the Game Directory text field.
        
     2. Select the directory where the game is installed.
        
     3. Press the ... button next to the Output Directory text field.
        
     4. Select the directory where the mod should be placed after building (preferably to the %game_root%/mods to avoid cutting/pasting the resulting mod).
2. Check the desired options from the list with checkboxes below.
   
3. Press the Build button.

If you want to reconfigure the mod, just repeat the above operations.

Put the PSEPSX.kpf file into the %game_root%/mods directory.
Example: C:\Program Files (x86)\Steam\steamapps\PowerSlave Exhumed\mods

Put the downloaded *.kpf file(s) into the %game_root%/mods directory.
Example: C:\Program Files (x86)\Steam\steamapps\PowerSlave Exhumed\mods

Replaces vanilla maps by the PSX ones.

• These maps do not support new difficulties (Hard and Pharaoh), so please don't play them on any difficulty level other than Normal.
  
• Checkpoints are unavailable on these maps (just like in the original PSX version).
  
• Kilmaat Colony is not replaced as the PSX map wasn't shipped with this product.
  
• There are fewer team dolls, and some of them are unobtainable because PSE requires a bit more dolls to unlock the special abilities that are required to get the rest.
