 +====== Metroid: Zero Mission Hex Tweaks ======
  
 +“Hex Tweaks” are loosely defined as sets of single-or-multiple-byte-changes that can be preformed for desirable effects. There is no clearly-defined upper limit for the number of bytes that can constitute a 'hex tweak' but they are usually less than 16 bytes' worth of changes. Most ZM hex changes are 2 byte changes. All that is needed to perform the hex tweak is a hex editor such as HxD. The tweak will give you an offset, original byte values, and the new values that you will enter in.
