'''MIX protectors''' are tools used to alter valid [[MIX|MIX files]] in a way that makes them unreadable with [[XCC Mixer]] and similar tools, but still leaves them working with the game they're coming from.

The primary technique used for this is mangling the header field storing the body size to generate an invalid value. Westwood's games seem to ignore the header information (thus allowing them to use the MIX despite the wrong header), while XCC compares the stated body size to the actual body size, and rejects the MIX as corrupt if there's a mismatch.
