    • Force High Memory Layout / Use Extra Memory (PRO/Adrenaline/ARK)
    • ISO cache / Inferno Cache (PRO/ARK)
    • Memory Stick Speedup (ARK/PRO)
  • On ARK standalone, you'll also need https://github.com/Kethen/NoPspEmuDrm/releases/tag/2025-07-02, update ur0:/tai/NoPspEmuDrm_kern.skprx and ur0:/tai/NoPspEmuDrm_user.suprx from the release
• Fix vita suspend, going to vita home/sleep while OUTSIDE of an adhoc session should be fine now
  • DO NOT go to vita home/sleep during an adhoc session, it will crash most games

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, currently you are also recommended to use DMZ/DMZ host, and avoid kd/pspnet_miniupnc.prx
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

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
