Transformers Autobots DS Cheats Not Working on Action Replay? Troubleshooting Guide

To troubleshoot, I need specifics. Please provide:

1. Exact Game Title: Transformers Autobots (2007, Vicarious Visions) or Transformers: Decepticons (separate SKU)?
2. Action Replay Hardware: Action Replay DS/DSi (white cartridge), Action Replay DSi/3DS (black), R4 / AceKard / DSTT (flashcart with AR cheat engine)?
3. Cheat Codes Used: Paste the exact codes (e.g., 120XXXXXX 0000YYYY). Are they for US (U), EU (E), or JP (J) region? Must match your ROM/cart.
4. Failure Mode:
   • Game crashes on load?
   • Cheats appear in menu but do nothing?
   • "No codes found" / "Unknown game"?
   • White screens / black screens?

Common Fixes

• Update AR firmware (CodeJunkies site — archived).
• Enable "Master Code" / "Must Be On" for that Game ID (e.g., YTWE 0A3B5C7D).
• Use TWiLight Menu++ + nds-bootstrap on 3DS/DSi (SD card) — better cheat support than original AR cart.
• Verify Game ID in TWiLight: YTWE (US Autobots), YTWP (EU), YTWJ (JP). Codes must match ID.
