    <abstract>
      <t>The <strong>TASD</strong> file format is used for storing "Tool Assisted Speedrun" or "Tool Assisted Superplay" (TAS) data for TAS replay devices to replay on physical video game console hardware.  The format is defined to be expandable for future needs.  The format is also defined to be parsable by programs that do not understand portions of the format, whether that is due to incomplete support of the format specification or due to new features being added to later versions of the specification at a later date.</t>
      <t>This document defines the file format specification for <strong>TASD</strong> files.</t>

      <name>Introduction</name>
      <t>The Tool Assisted Speedrun Dump (<strong>TASD</strong>) interchange format is a file format for storing data to allow "Tool Assisted Speedruns" or "Tool Assisted Superplays" to be played on physical video game console hardware using TAS replay devices.  Created to be hardware and software agnostic, the <strong>TASD</strong> interchange format uses a key-based, binary, packet format to break up pieces of information into easily-parsable and forward-compatible chunks. The format is extensible by simply defining additional keys or value types as necessary. When parsing the file, software can skip any packets whose key is unknown or unsupported.</t>
      <t>Keys can be used multiple times or completely omitted as needed. This reusability eliminates the need of a predefined delimiter to separate pieces of data such as a list of TAS authors.</t>
      <t>While files generated by emulator dump scripts should provide as much information as possible, because keys are optional, the file can be expanded later with any additional data as desired. No intermediary file format is necessary.</t>

          <name>Notation and Vocabulary</name>
          <t>Data Types:</t>
          <ul spacing="compact" empty="true">
            <li>(S) = String</li>
            <li>(A) = Binary Data</li>
            <li>(I) = Signed Integer</li>
            <li>(N) = Unsigned Integer</li>
            <li>(B) = Boolean</li>
            <li>([]N) = List of Unsigned Integers</li>
          </ul>
          <t>We use the terms <strong>byte</strong> and <strong>octet</strong> interchangeably in this document.</t>
          <t>Unless specified otherwise, all multi-octet integers are big-endian.</t>
          <t>We use the terms <strong>Tool Assisted Speedrun</strong>, <strong>Tool Assisted Superplay</strong> and <strong>TAS</strong> interchangeably in this document.</t>
          <t>In subsections of (<xref target="descriptions" />), the term "in direct form" is used.  That term is defined to mean a packet in a <strong>TASD</strong> file directly (first order packet) rather than a packet inside a TRANSITION or MOVIE_TRANSITION packet (second order packet).</t>
          <t>String values <bcp14>MUST</bcp14> use UTF-8 encoding.  If an example of a string value is given, the example will be between quotation marks.  The quotation marks are not included in the string.  Not all content between quotations will be string value examples, so be aware of that when continuing through this document.</t>
          <t>Unsigned and signed integers can have different bit widths.  For instance, an 8-bit integer can be used in one part of the specification and a 64-bit integer can be used in another part of the specification.</t>
          <t>Boolean values <bcp14>MUST</bcp14> be a single octet with the value of <tt>0</tt> for <strong>FALSE</strong> or <tt>1</tt> for <strong>TRUE</strong>.</t>
          <dl>

          </dl>
          <t>In packet diagrams, a single octet is represented with a box like this:</t>
          <artwork><![CDATA[

          <t>In packet diagrams, an arbitrary number of octets are represented with a box like this:</t>

            <li><strong>Var</strong> is a variable name.</li>
          </ul>
          <t>In packet diagrams, boxes can be connected like these examples:</t>

      +-----------+-----------+]]>
          </artwork>
          <ul spacing="compact" empty="true">
            <li>In this example, <strong>Var 1</strong> is a 1 octet long boolean value and <strong>Var 2</strong> is a 1 octet long signed integer.</li>

          <t>In packet diagrams, boxes <bcp14>MAY</bcp14> have relative offset values above them like in the following example:</t>

          </ul>
          <t>Packet diagrams <bcp14>MAY</bcp14> be split into multiple lined sections like in the following example:</t>
          <artwork><![CDATA[

          <ul spacing="compact" empty="true">
            <li>In this example, enough variable boxes are in the packet diagram to require being split into 2 sections to take up less horizontal space in this documentation.

        <name>Motivations</name>
        <t>This file format's primary goal is to provide a comprehensive and replay device agnostic TAS movie controller input dump format that is usable for any console.  Additional goals include:</t>
        <ul>
          <li>No intermediary formats</li>
          <li>Forward compatibility</li>
          <li>High extensibility</li>
          <li>Ability to easily generate using lua scripting in emulators</li>
        </ul>
        <t>Consideration was also given to how usable the format would be for the software that interacts with replay devices (examples: methods of ingestion/parsing, ease of ingestion/parsing in various languages).</t>
        <section numbered="true" toc="default">
          <name>Problems With Existing Formats</name>
          <t>Most existing formats are either incomplete for some verification needs or don't exist at all for some consoles.  A format commonly used for NES console verifications (r08) only encodes 2 standard controllers worth of sequential data and a format commonly used for SNES console verifications (r16m) only encodes up to 8 standard controllers worth of sequential data.  There is no built in way to store <strong>RESET</strong> press timing information or indicate additional settings/information.  Non-standard controllers are also not supported in commonly used formats.</t>
          <t>For consoles not as popular as the NES and SNES, controller input formats would frequently be written in a way that is meant only to work and not in a "standard" way.  While that process works, it's less than ideal for redistribution of console replays so that others (especially with differing TAS replay devices) can also verify the same TAS.</t>
