you can get Firefox on your PSP!
The pictures don't look photoshopped (legit?)
I can't test it because I upgraded my psp to 2.71
From the site:
Welcome to the new home of the Firefox on PSP Project.
This is a new homebrew application that allows you to run firefox on your 1.5 psp.
I will be posting (more) pictures and videos soon.
Because this has a risk attached to it and it is not stable, it will not be released to the public until it becomes more stable. If you really want to risk bricking your PSP to beta test this, contact me.
