As there are other topics explaining how to use the PRO Online Client - I won't go into details on how to use these files.
In this topic you will always find the latest public builds of the client!
To ensure best game compatiblity, please make sure you stay updated! Outdated clients can (and most likely will) cause problems!
Enabling the UPNP Library when UPNP isn't available freezes PSP at times.
Solution: Enable UPNP in your Router or remove the UPNP library (pspnet_miniupnc.prx) from the /kd Subfolder (don't forget to DMZ your PSP if you do this).
In some games the home menu is invisible. We are going to work on it.
Existing versions of RemoteJoyLite crash when using PRO Online. You can download a working version for UMD based PSP models from here.
The version linked above has been modified to use the PRO CFW high memory range and thus only works if high memory has been enabled.
It also works on PSP Go, however not when PRO Online is active, I'm investigating the matter.
