Link Play & Modtopia mods

How Link Play multiplayer works in Recompia

Link Play puts multiple players on the same island over Wi-Fi/LAN or across the internet, and supports cross-play with xFractals/pokopia-native players on game version 2.0.1 (players on older game version 1.0.5 cannot join). Every player must have their own distinct save file; a copied save file shares the same Player ID and triggers Communication Error 9005.

Step-by-step Link Play setup (LAN & Internet room codes)

1. Configure the launcher before starting: open PokopiaLauncher, go to the Link Play tab, and choose:
   • Same network for home Wi-Fi/LAN.
   • Internet → Host (to generate a room code to send to friends) or Internet → Visit (to type a friend’s room code). In v0.11.1, the launcher connects to the permanent public Recompia relay automatically. (If you are still on v0.11.0, enter 204.216.111.91:47610 under Link Play > Advanced > Use my own relay or address.)
2. Allow Windows Firewall on first host: when Windows Firewall prompts for pkp.exe, tick Private networks, and make sure your Windows network profile is set to Private (Settings > Network & internet > Network profile type: Private).
3. Open the in-game PC terminal: Link Play becomes available in-game after reaching Environment Level 2 in the Withered Wasteland. Interact with the PC inside your first house, select Link Play, and choose Local connection (never pick Online connection, which is Nintendo’s console service).
4. Host or join: the host selects Invite Others to Visit; visitors select Visit a Friend.

Interact everywhere & Story co-op (experimental): By default, visitors in story areas are placed in Spectator Mode. Turning on Interact everywhere lets visitors use moves, items, pick up, place, and build there; Story co-op also lets visitors talk to story characters. Every connected player must have the exact same Interact everywhere and Story co-op toggles enabled, and the same gameplay mods, or the host will not appear in the list. Only the host’s save records story progression.

Modtopia (.pkmod) mod loader & launcher Browse hub

Starting in v0.11.1 and expanded in v0.12.0-beta.1, Recompia runs mods built for Modtopia, the mod loader shared with pokopia-native:

• Installing & browsing .pkmod mods: open the Mods page in PokopiaLauncher. In v0.12.0-beta.1 (#578), switch to the Browse tab to filter the Modtopia hub by group, inspect full mod descriptions, settings, download sizes, and Tested badges, and install or update with one click. You can also drop .pkmod files straight into the mods/ folder.
• Code permission & incremental hook compilation: a mod that contains executable code runs only after you explicitly allow it on the Mods page (mods with only replacement data files need no permission). If an enabled code mod needs hook points in the game binary, the launcher shows a Set up again banner: in v0.12.0-beta.1 (#569), it re-translates only the touched module (~4.5 minutes for main-only hooks, under 1 minute for hooks outside main) without rebuilding shaders.
• In-game Mods tab & Start without mods (v0.12.0-beta.1): open the game’s own Settings screen to view the Mods tab (#567), adjust live mod settings, or hide the HUD (Photo Mode / Hide HUD via ui_visible, #577). If a mod causes an unexpected exit, use Start without mods in the crash prompt or under Settings > About > Troubleshooting (#580).

Layered romfs_mod folder structure (textures & translations)

To layer loose replacement files (such as a translation or texture pack) without modifying your dump, select the mod’s inner romfs folder under Settings > Game > Mods (or set romfs_mod under [fs] in pkp.ini). The chosen folder must match the top level of the game’s own romfs (the directory containing LD_C0_R.BIN and LI_C0_R.IDX):

MyTranslationMod/            <-- pick this folder in Settings > Game > Mods
├── LD_C0_R.BIN              <-- must sit at the top level of your chosen folder
├── LI_C0_R.IDX
└── motor_asset_re/
    └── ...

If a downloaded archive wraps those files inside an outer path like 2.0.1/romfs/LD_C0_R.BIN, select the inner romfs folder. If the level is wrong, pkp.log reports that zero mod files replaced a game file. Note that mods replacing shader archives are not supported.
