Step 1: Things You'll Need
2. A PC (to get the files)
3. An USB cable or an Memory Stick adapter
4. A Memory Stick (with at least 20 MB free (I don't have the exact MB # that PSPKVM and Opera Mini takes but I think that 20 MB should be enough))
5. An Internet connection (both on your PSP and in your PC)
Step 2: Get Files
Step 3: Let's Begin
Choose the device J2ME 480*272 (this adjusts Opera to the PSP screen size).
Wait to it to finish.
Click on it to start Opera Mini.
To change the settings...
Launch Opera Mini.
Go to Menu>Tools>Settings.
You can choose an custom color theme, font size (I recommend small), and more.
