So your probably asking how the hell did I do this, well here's how.
You will need:
An hacked PSP (Phat or Slim) I haven't tested this on the HEN, but I'm pretty sure it might work.
An PC (to get the files)
An USB cable or an Memory Stick adapter
An 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))
An Internet connection (both on your PSP and in your PC)
Got that? Let's start.
First, get PSPKVM 0.5.4 app here.
Place in the folder X:/PSP/GAME5XX/ were X: is the letter of your drive (copy the ENTIRE pspkvm folder!).
After that upgrade to 0.5.5 test 2 version by downloading the 0.5.5 EBOOT here.
Put the EBOOT into X:/PSP/GAME5XX/ , confirming overwrite.
Then, get the Opera Mini files from the following URL's:[You must be registered and logged in to see this link.][You must be registered and logged in to see this link.]
Download the two files and place them in the root of your Memory Stick (were you can see all the other folders).
You're almost done!
Now, unplug your PSP from your PC and go to the GAME menu on the PSP, and launch PSPKVM.
If you haven't set up an Internet connection, choose "Network Set-up" (remember, in this app ENTER is with O, not with X, however, this option can be changed by going to SYSTEM MIDLETS>CONFIGURE VM>KEYMAP SETTINGS).
Now, go to "SYSTEM MIDLETS>FIND APPLICATIONS", and select the file "opera-mini-advanced.jad" from ms0:/ (should be on the root). Press O and it should ask you if you want to install the app, click yes (the bottom options are with [Select] and [Start] if you haven't already figured it).
Choose the device J2ME 480*272 (this adjusts Opera to the PSP screen size).
Wait to it to finish.
If you did everything correctly, "Opera Mini" should be now on your main PSPKVM menu.
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, and more.
"Not enough memory" errors are over!
Have fun with it!
These are OPTIONAL, they're not required for Opera to work.
You (should) get Opera for PC as you can synchronize your PC bookmarks to your PSP without the need of moving any file.
Use the "Mobile View" mode to reorganize the page for an optimized view.
How to use PSP OSK instead of bulit-in Java keyboard
If you're using the newest PSPKVM version, there's no need anymore to edit any file, as it's now configurable:
Just start PSPKVM, and go to SYSTEM MIDLETS>CONFIGURE VM>VIRTUAL KEYBOARDS.
You're done! Now typing should be A LOT faster!
Note: To bring it up choose "QUERTY" in the menu (when typing in Opera Mini). Then press any button. It should pop up. Do your typing, and click ok. You should know the rest.
To undo just go again to SYSTEM MIDLETS>CONFIGURE VM>VIRTUAL KEYBOARDS and choose the keyboard you want to use.
Opera Mini v5 Beta info:
I know there's an newer Opera version released, but it runs slow like hell. Stick to this one.
