If you encounter this file outside its original game: Part 7: Ethical and Legal Considerations While this

Missing file – The game may fail silently or disable the multiplayer button. No crash is expected if truly optional.
Corrupted file – Multiplayer sessions will likely fail with a checksum error or desync warning. Single-player remains unaffected.
Modding – Replacing or hex-editing this binary can alter network behavior, but beware of anti-cheat systems (e.g., Easy Anti-Cheat may hash it).
Extraction – Tools like binwalk or nomnom may reveal embedded PNGs, JSON, or ZLIB chunks.

Advanced: Manually Extracting `fg-optional-multiplayer-build.bin`

For advanced users who want to skip the repack installer entirely, you can extract the .bin manually using FreeArc or InnoExtractor. However, this is not recommended—the setup script applies necessary registry keys and crack files specifically for multiplayer.

If you still want to try:

Download InnoExtractor.
Open Setup.exe from the repack.
Navigate to “Files” → Locate the entry for fg-optional-multiplayer-build.bin.
Extract the contents directly into your game’s root folder.
Manually copy any multiplayer crack (usually inside a CODEX or PLAZA folder).

But again: stick to the FitGirl installer unless you are very experienced.
