2025-07-29 PRERELEASE

on GitHub

Changes:

• Fixed nonblocked ptp socket connection failing on higher latency connections, thanks @SilverJolteon for sending logs

Installation:

1. Make sure you're on at least cfw 6.60, on PSP 2000/3000 or PSVita Adrenaline / ARK standalone
2. Copy seplugins and kd into your PSPs memory stick ms0:/, or ux0:/pspemu/ for Adrenaline / ARK standalone
   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)
   1.6 On PSVita, if you must use upnp, please also use https://github.com/Kethen/pspemu_inet_multithread , otherwise please use DMZ/DMZ host
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, disable these options when available

• Force High Memory Layout / Use Extra Memory (PRO/Adrenaline/ARK)
• ISO cache / Inferno Cache (PRO/ARK)
• Memory Stick Speedup (ARK/PRO)

1. On Adrenaline and PSP, make sure WLAN power saving is disabled in vsh -> Power Save Settings -> WLAN Power Save, as @ sorer also reported weird behavior being observed when that is on
2. On PSVita, disable WLAN power saving in home -> Settings bubble -> Power Save Settings -> Use Wi-Fi in Power Save Mode
3. If you wish to override your nickname (mostly on ark standalone), add a text file ms0:/seplugins/nickname.txt, ef0:/seplugins/nickname.txt, or ux0:/pspemu/seplugins/nickname.txt containing your nickname. For best compatibility, avoid special characters and symbols, stick to ascii encoding.

When using the debug prx-s, logs can be found at ms0:/atpro.log

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
