Modding Star Trek: Legacy on Xbox 360 – Not Possible from PC

You cannot install mods on the Xbox 360 version of Star Trek: Legacy from a PC. The Xbox 360 is a closed platform — no official mod support, no file explorer access, and the executable is signed/encrypted.

Why It's Blocked

• Code Signing: Every .xex must be signed by Microsoft private key. Modded files fail verification.
• No User File System Access: No "My Documents" for game mods. Data lives in hidden partitions (Content/000000000000...).
• No SDK Tools: Modding tools (Legacy Mod Manager, ship packs) are Windows-only and output loose files / repacked .big archives — unusable on 360 without resigning (requires dev kit / leaked keys).

What You Can Do

• Play on PC (Steam / GOG / Disc): Full mod support. ModDB has 100+ mods: new ships (Eraudi, Voth, Kelvin), missions, graphics overhauls (DX10/11), total conversions (Star Trek: Legacy - New Horizons).
• Xbox 360 RGH/JTAG: Homebrew enables XexMenu / Aurora / FSD to launch modded .xex — but you must resign the modded .xex with a valid KV (banned console) or use XeXLoader with patched kernel. Extremely complex, high ban risk, no community support for Legacy mods.
• Save Editing: Transfer save to PC → edit with Horizon/Modio → transfer back. Limited to credits, unlocks, not gameplay mods.

Bottom line: Buy the PC version (often <$5 on sale). Modding on 360 is a dead end.
