Detailed guide (for people who doesn't know what terms I'm talking about) :
1. Download and run X360CE.
2. Set your keyboard to Controller 1, click the Add button (refer to the image above).
- It will open this menu (refer to the image below).
3. Choose your keyboard and click "Add Selected Device", you have set your keyboard on Controller 1 (refer to the image above).
4. Do the same in Controller 2, set your controller to Controller 2 (refer to the image above).
- It will open the same menu (refer to the image above in Step 3).
5. Choose your controller and click "Add Selected Device", you have now set your controller on Controller 2 (refer to the image above in Step 3).
- You have set your controller to Controller 2, remap the controls if the mappings are blank/empty.
6. Load a game in BBPSX, enable Local co-op.
7. After you loaded a game, go to Controller 1, and untick "Enable 1 Mapped Device" to disable Controller 1 (the red square indicator shows it is disabled) (refer to the image above).
- You can now play the game! (Minimize X360CE, not close.)
- If it doesn't work, relaunch the game, or invert it (set your keyboard in Controller 2, and set your controller in Controller 1.)
- This is the quickest/best method in my opinion since there's no actual Splitscreen control settings for now.
