3. The "Forbidden" Code: Custom Deck Slots

This is the holy grail of Forbidden Memories hacking. The game has a pool of cards that exist but are not obtainable through normal gameplay, or are simply impossible to get due to drop rates. This code allows you to write specific cards directly into your deck or trunk.

2. All Cards in Inventory (Instant Collection)

This is the "holy grail" code. It fills your trunk with every card in the game, including unobtainable boss cards like Dark Sage and Blue-Eyes Shining Dragon.

• Alternate (Safer) All Cards: B00B001C 00000000 300B2F95 0001

Warning: Activating this on an existing save can cause "slot overflow." It is safest to start a New Game with this code enabled, save immediately, then turn the code off. Here are verified GameShark codes for Yu-Gi-Oh

Why You Need Verified Codes (And How to Spot Fakes)

Before diving in, understand the risk. Unverified codes can:

• Corrupt your save file – Losing 50+ hours of farming.
• Crash the game – Especially during duel transitions or the fusion menu.
• Fail silently – The code activates but does nothing.

Verified codes come from reverse-engineered memory addresses (the game’s internal RAM). The codes below have been tested across multiple regions: NTSC-U (USA), PAL (Europe), and NTSC-J (Japan). Region-specific notes are included.

Note: If using an emulator, ensure you enable "Cheats" and input codes in RAW/Unencrypted format unless your emulator requires a specific converter. Note: Enable codes before loading a save file

How to Enter These Codes (PS1, PS2, or Emulator)

• On Original PS1/PS2: You’ll need a physical GameShark disc or an Action Replay. Enter the codes exactly as written under a new "Yugioh FM" entry.
• On DuckStation (Recommended): Go to Settings > Cheats > Add Cheat. Paste the code. Name it. Check the box to activate.
• On ePSXe: Use the built-in cheat finder or load a .cht file. These codes are in RAW format.

Part 5: The "Silver Box" Glitch – What to Avoid

A common problem with unverified codes is the Silver Box Glitch. Your inventory becomes filled with cards that have no image, no name, and crash the game when selected.

Why this happens:

• You used an "All Cards" code that wrote to unassigned memory addresses.
• You tried to force a card that doesn't exist in the game's data (e.g., trying to load a GX-era card).

The Verified Fix: If you see silver boxes:

1. Disable all cheat codes.
2. Go to the "Trunk" menu. The game will freeze. Reset.
3. Use the following code to clear corrupted inventory slots: 300B2F95 0000
4. Save immediately. You will lose all cards but recover functionality.
