@@ -11,7 +11,7 @@ To restore your PSP, follow a simple instruction:
     - a 10kOhm resistor (not required); 
     - a way to connect to battery contacts (anything from loose wires to connector from a sacrificial battery)
     - soldering equipment or breadboard with jumpers
-2. Build your probe - one-wire UART (aka K-line) adapter. You can omit an external battery if you power your PSP with a DC charger. Be aware that adapter's power output alone is not sufficient to power the PSP. You can also omit 10kOhm diode.![Yoti's_schematic](https://user-images.githubusercontent.com/82090925/129186282-6d036e88-fab3-4fac-9b2a-7ac2bf7f9628.png)

 3. Create a Magic Memory Stick compatible with PSP-3000. You need to use either an official JigKick MS clone or balika011's DDCv9 - you can create both with my tool (https://github.com/khubik2/JigKick-Media-Creator)
 4. To start the emulator, install necessary pip packages: `pycryptodome`, `tk` and `pyserial`.
 5. Insert your memory stick and connect your adapter to computer running the emulator, select the COM port of your adapter and start the service.
