We now have a Hotline server at PSP/PSVita Fans! Point your Hotline client to "psp.gameplayer.club" or look for the server "Sony PSP & PSVita game archives" in the list and get the 500 files in the repo (note these are the same as what you can get from our Website/FTP servers).
If you want a custom user name for the server choose the Request User Name menu option.
