Changes:

• Improve pspnet_miniupnc.prx stability, it should survive connect/disconnects way better now
• Improve pspnet_miniupnc.prx logging, if your router is not cooperating, it should be logged better now in the debug prx.
• Fixed a bug where the debug prx-s could crash in some games

Note: Please avoid using other pspnet_miniupnc.prx with this release and onward. If you do so and it does not work, I really can't help you with it.

Installation:

1. Make sure you're on at least cfw 6.60, on PSP 2000/3000 or PSVita Adrenaline
2. Copy seplugins and kd into your PSPs memory stick ms0:/, or ux0:/pspemu/ for Adrenaline
   1.5 Remove kd/pspnet_miniupnc.prx if you don't plan to play on the internet, or your router does not support upnp (You'd need DMZ/DMZ host, then)
3. Update seplugins/server.txt with the match making server of your choice
4. If seplugins/game.txt do not yet exist, create it, then add ms0:/seplugins/atpro.prx 1 to seplugins/game.txt. If you're on ark cfw, please change this step according to https://github.com/PSP-Archive/ARK-4/wiki/Plugins
5. Update seplugins/port_offset.txt to match your PPSSPP's configuration, PPSSPP's default is 10000
6. In your cfw's recovery menu, disable all game plugins except for atpro.prx. If you're on ark cfw, please change this step according to https://github.com/PSP-Archive/ARK-4/wiki/Plugins
7. In your cfw's recovery menu, enable force high memory layout and disable iso cache

Note:

I've only tested this on LAN, with a PSVita 2000 Adrenaline, a PSP 2000 procfw and PPSSPP
Game compatibility is hopefully as good as the original release
