every command is present and binary accurate): The following ABI files are currently provided, and are known to be functionally complete (i.e. In SEQ64 V1, each ROM had its own "RomDesc" file, including the Music Macro Language format definition as well as the bank binary format definition, the addresses of key files and tables, and program settings. As the Music Macro Language format changed between games, these changes can be represented by swapping or editing these files, rather than editing and recompiling the program. In the case of SEQ64 V2, this means the definition of the Music Macro Language format-what all the commands do, what format their parameters are, etc.-is stored in an "ABI definition" XML file. One key design decision of SEQ64 is that as little is hardcoded as possible. It can still be downloaded from the Releases tab above, if you need these features. It also was able to use General MIDI instrument and pitch metadata annotated by the user in the banks to export MIDIs which sound reasonable with General MIDI playback. aseq), as well as a bank editing and creation tool. At this time, the assembly version of Music Macro Language was only theorized to exist-in fact the format was only theorized to be "Music Macro Language" at all (later versions of this language were used in first-party Nintendo games as late as Skyward Sword). It got widespread use by the community, but almost exclusively for MIDI importing and then Save Raw (. SEQ64 V1 was started in an era when romhacking tools took whole ROMs and modified certain files in them while being careful not to disrupt any other data. In a modern, decomp-based romhack environment, use AudiobankToC for bank editing. SEQ64 V2 does NOT currently include any bank editing or MIDI instrument number conversion to General MIDI (SEQ64 V1.5 included these features). Nevertheless, workarounds were put in place, and SEQ64 matches on. This is no easy task: for example, the sound effects sequence from Ocarina of Time is over 17,000 lines long, and contains bugs (in the actual in-game version) which make the sequence technically invalid. Crucially, SEQ64 aims to-and succeeds in several key cases-match the game data byte-for-byte when converted from binary to assembly or MIDI and back again. This means that existing sequences can be exported and edited-either to MIDI for music or to assembly for sound effects and technical sequences-and then re-imported into the game. SEQ64 V2 converts among any of these three formats: MIDI (. Of course, a music sequence, though not the sound effects sequence or other technical sequences, can also be represented (at least mostly) as a MIDI file, and the music in these games was originally created as MIDIs and then converted to. m64, though this extension was already taken for Mupen 64 format TAS replay files). mus, and a binary format used in the games with the canonical extension. Music Macro Language exists in two forms: a text-based assembly language in files with the extension. This sequence is a huge "program" written in this language which listens for messages from the game engine and then plays miniature sequences for each of these sound effects. In games which use this format, not only are MIDI-like music sequences stored in this format, but the first sequence in each game handles sound effects. This format can be thought of as a cross between MIDI and a scripting language such as Python: it contains instructions for things like playing notes, pitch bend, and selecting instruments, and also programming instructions like branches, loops, calls, memory I/O, and some basic variable manipulation. BackgroundĬertain Nintendo 64 games made by Nintendo's internal studios, including Super Mario 64, Zelda, and several others, use a music sequence format called Music Macro Language (formerly referred to as Audioseq after the name of the file containing the sequences in the OoT Debug ROM). If you are using an old-school toolchain which doesn't split the ROM into its constituent files, but where you just edit the whole ROM in one tool after another, use SEQ64 V1.5. The rest of this README explains in more detail. m64 are all the same thing (Music Macro Language binary).mus is the text-based assembly language version of this same data. mus? What is all this?
