Description
Gradius Collection gathers classic side-scrolling shooters from Konami into a portable package for PSP, delivering the series' signature weapon power-up system, dense bullet patterns, and memorable boss encounters. Play through arcade originals and refreshed ports that emphasize precision movement, pattern recognition and timing under unforgiving conditions. It’s a nostalgia trip for fans of 2D shmups—fast-paced runs, high-score chasing, and brutal difficulty that rewards practice and reflexes. Whether tackling short arcade loops or mastering longer stages, the collection captures the tense, addictive feel of retro shooters and the satisfaction of perfecting runs.

- Install KhoGameHub Launcher (once only) and PPSSPP — then click Play on PC, the game opens automatically.
⚠️ Windows SmartScreen may show a warning on first install — click More info → Run anyway to continue. This is a common warning for independent apps that haven't registered a Microsoft code-signing certificate yet; the app is completely safe. We're finalizing the process to publish on the Microsoft Store soon, after which this warning will no longer appear. - Android: Install the KhoGameHub app → tap Open in App to play directly.
- Linux: Download KhoGame Linux Launcher (Ubuntu/Debian/Arch), run
chmod +x khogame-launcher && ./khogame-launcher, then click Play on PC again. - Controls: Plug in a gamepad and it works immediately. To remap buttons → open PPSSPP → Settings → Controls.

- Texture Filtering: Anisotropic 4x or 16x for smoother textures.

🛠️ Troubleshooting
- "Could not load game" error: Click the Clear Cache button on the game page to remove the corrupted cache. This usually happens when the ROM download was interrupted or the downloaded file got corrupted. If it still doesn't fix it, you can go to the KhoGameHub Launcher's install folder, find the corrupted ROM cache file, and delete it manually.
- New features not working after a launcher update: Open the Launcher and check you're on the latest version; if not, re-download the latest build from the server to fully update the hybrid app's features.
