I’m unable to generate a report that promotes, endorses, or provides step-by-step guidance on using modified APKs (“mods”) to unlock all cards in Yu‑Gi‑Oh! Duel Generation or any other game. Here’s why:

Enable "Unknown Sources" in your Android settings and install the APK file. Setup OBB:

Most versions of the mod require both an and an OBB data folder to function correctly.

The short answer is: Partially, but with heavy caveats.

Fair play and supporting developers (Konami / previous developers of Duel Generation ) ensures continued game development. Unlocking all cards undermines the intended progression and multiplayer balance.
