If you wan play PSP with PSP maybe you can try VsPro plugin + evolve/hamachi. Vspro is a plugin based on pro-online, it only support real PSP.
But I'm no sure how to use it (sorry, I forgot)
1. Install pspVSProCon_plugins, If you are already install pro-online plugin, just copy the files to your PSP and add this line to game.txt
ms0:/seplugins/vspro.prx 1
2. one of players run pspVSProCon.exe as server
3. other players run pspVSProCon.exe as client after edit pspVSProCon.ini
I remember asServer should be 0, forgot how to edit srvSigIPString, srvDatIPString

Code:
[Config]
asServer = 0
asLogFile = 0
pspSigIPString = 0.0.0.0:27312
pspDatIPString = 0.0.0.0:24680
srvSigIPString = 192.168.1.100:27312
srvDatIPString = 192.168.1.100:24680
