I made this thread after receiving several PMs from people asking for the portal.
Here it is!
Just for those who don't know: PSP Mega Portal is a portal that can look like various styles of windows, linux, and mac. You choose the os that you want to use (well not really use - just the portal of it) at the main page.
Install guide: put the 'mega' folder at 'X:\PSP\COMMON\', where 'X' is your PSP's drive letter.
to use, go to 'file:/PSP/COMMON/mega/home.htm' on your PSP.
Note: I did not make this portal, I am just posting it here for others to download.
To whoever controls dl.qj.net: Please feel free to add this to the downloads site.
EDIT: oops, posted in wrong place - mods please feel free to move...
