Music hacks are relatively rare in most hacks, due to the wide variety of ways games store music data (hence the difficulty in locating and modifying this data) as well as the difficulties in composing new music (or porting music from another game). As music cracking is very uncommon, many hacks do not have any ported/composed music added in. Exceptions canexist, besuch foundas inthe most recent ''[[Super Mario World]]'' hacks where new music can have new instruments not found in the original game. Other games that have music hacking as part of their research and hacking communities are the NES ''[[Mega Man]]'' games, ''[[Final Fantasy VI]]'', and the Mega Drive (Genesis) ''[[Sonic the Hedgehog]]'' games.
As many Game Boy Advance games use the M4A Engine (alsoinformally called "Sappy Driver" and officially known as "MusicPlayer2000" or MP2k) for music, the program SapTapper can be used to hack Game Boy Advance music data. Various other utilities were created to work with the engine such as [https://web.archive.org/web/20160306150654/http://www.pokemonhackersonline.com/showthread.php?t=120-Wataru-Kun-s-Ultimate-Pok-mon-Music-Hacking-Guide Sappy 2006]. Another instance of the same engine being used between games is on the Nintendo 64 where most games use the same format; albeit with different sound banks. A utility known as the [https://github.com/jombo23/N64-Tools/tree/master/N64MidiTool N64 Midi Tool] was created to edit the sequences that the majority of Nintendo 64 games use, however it does not cover first-party N64 titles that use a slightly different engine such as ''[[Super Mario 64]]''.
