Step 1: Open the Control Panel on your desktop.
Step 2: Inside the Control Panel open Java. (You might have to click on the Security tab and then request access to the Java control panel at the bottom of that security-related window.
Step 3: Under Java/Security, click the security tab. You will see the Java version information in the Java Control Panel.
Step 4: Press the YES button to have the JAVA verifier check the JVM for you. You will be told if any security problems exist.
Step 5: Press the OK button and the Close button to verify Java and exit the JAVA Control Panel.
Step 6: Close the Control Panel. You should now be able to run the spu2-x version 1.8.1 emulator.
Step 7: Look for a file named spu2-x.jar under the C:\Program Files\spu2-x directory. The spu2-x version 1.8.1 emulator will run properly from this .jar file.
Step 8: Run the spu2-x version 1.8.1 emulator. A command prompt window will appear and a Windows alert will sound asking if you want to allow it to make changes. This is normal, so give permission.
Step 9: On the left side of the command prompt window you will see a window that says “spu2x – version x.x (build yy)” followed by some version numbers and a (build yy) number.
Step 10: If things are working properly, you should see a little menu that includes the following options shown at the top of the menu as “File + Emulator.”
