Project Cuga v0.1.0-test.1 — Windows portable

Newer Windows FUC release available: Project Cuga 0.1.4. The newer update includes FUC feature corrections, HD texture pack support and frame interpolation fixes, but has not been extensively tested. The older download remains available below. Back up saves before updating.

Experimental test build. This is Cuga's first packaged Windows preview, not a stable or fully tested release.

Download Project-Cuga-0.1.0-test.1-Windows-x64-portable.zip below, extract the entire folder, and double-click Cuga.exe. You do not need a compiler, SDK or emulator.

Your own game files are required

On first launch, select your own MHP2G ULJM05500/FUComplete ISO. Setup prepares the executable locally. Supply FUComplete's required FUCDAT support folder from your own patch setup under data/ms0/PSP/SAVEDATA/FUCDAT; it is not in this download. The included README also explains how to use an existing prepared game/ folder instead.

No disc image, original PSP executable, extracted game assets, save, personal settings, cloud files, network nickname, server configuration or signing key is included. Online play and optional quest/shop/map/restock/loadout QOL additions start disabled. A new player configures their own connection and preferences.

Loadout warning

The loadout feature is not yet fully functional. Saving, loading and restocking loadouts is experimental. Check your pouch manually and keep a backup. Loadouts start disabled.

Included and tested

• Windows x64 Cuga executable, 298 matching compiled runtime overlay DLLs, SDL3, FFmpeg and app-local Visual C++ runtime DLLs.
• Better Shop, Key Quest Stars and capture skull support, including skulls with Monsters on the map. Enable desired options under QOL.
• Distribution mode removes the development game-directory fallback and debug tools.
• Clean extracted-folder setup and boot with a privately supplied ISO/FUCDAT passed on the development PC.
• Quest/skull, shop and cloud-save regression tests passed. Dependency, privacy, game-file exclusion, ZIP integrity and checksum checks passed.

Requires 64-bit Windows 10/11 and a Vulkan-capable GPU with a current driver. Not verified on a separate physical computer, every GPU, all quests or a full multiplayer regression run. This release is Windows only.

Keep data/ and any game/ folder when updating; they hold your own progress/game files. Cloud saves start disconnected and need your own setup. See the ZIP's README for installation, save import, troubleshooting and uninstall instructions. SHA256SUMS.txt verifies the download.
