How to install opera web browser on your PSP

NOTE:IN ORDER TO INSTALL OPERA YOU SHOULD HAVE CFW ON YOUR PSP

 With this guide you'll be able to use the opera mini browser on your PSP instead of using the built-in browser.


You will need:
-PSPKVM
PSPKVM is a homebrew java program that allows you to run programs that have the .jar extension, as of version 0.3.2 there is an on screen keyboard (osk), thus allowing for easy web browsing. PSPKVM was not made in the US so if you use X for enter and O for cancel, the buttons are switched on this.
-Opera Mini
Opera Mini is a web browser that is designed for cell phones.

INSTALLATION
Step 1: Download PSPKVM and Opera Mini via the download links above.
PSPKVM goes in ms0:/PSP/GAME
Opera Mini.jar goes in ms0:/PSP/GAME/PSPKVM/Apps
Step 2: Launch PSPKVM from the XMB. When loaded, click on "Find Application" and browse to the Opera mini location (ms0:/PSP/GAME/PSPKVM/Apps) and select it. It will ask you to select a device, choose "J2ME Standard (480*272)"
Step 3: Connect to your wireless connection by selecting "Yes" when asked if you would like to use airtime.
Step 4: Once connected, accept the EULA by pressing select. You're then free to use it any time you want instead of the built-in browser.
