Title: Verified Gameshark Codes for Yu-Gi-Oh! Forbidden Memories (PS1) – No Fake Lists
Body:
After weeks of testing and sifting through broken code lists from the early 2000s, I’ve put together a set of verified Gameshark codes for Yu-Gi-Oh! Forbidden Memories (NTSC-U version). These work on real hardware (PS1 with Gameshark/Action Replay) and most emulators (ePSXe, DuckStation, RetroArch with PCSX-ReARMed). Title: Verified Gameshark Codes for Yu-Gi-Oh

Lets you fuse any two cards regardless of star alignment.
Q: Do these codes work on PS3/Vita via PSN Classics? A: No. Sony's PSN emulator wrapper blocks raw Gameshark codes. You must use a CFW (Custom Firmware) or stick to original PS1 hardware/emulators.
Q: I entered the Master Code, but nothing happens. A: Double-check your game version. Go to the main menu. If it says "Konami 1999" in yellow, you have USA. If it has multiple language options, you have PAL. Use the correct Master Code. Save before activating any code
Q: Will these codes unlock the "alternate ending"? A: Yes and no. The game's ending is based on your Star rank. Using the "Max Stars" code will allow you to fight the hidden boss (Heishin 3 / DarkNite), unlocking the mythological "Perfect Ending" with the full credits montage.
Q: Are there Gameshark codes for the "Fusion Glitch" (Twin-Headed Thunder Dragon)? A: The fusion glitch is a mechanical exploit, not a code. To perform it: Fuse two Thunder Dragons into Twin-Headed, press X during the lightning animation, and quickly swap the third card. Codes can make this easier by slowing down framerates (use emulator throttle).
Some cards like Skull Knight or Perfectly Ultimate Great Moth are coded into the game but cannot be fused normally. This code re-enables them.
