TASD File Format Specification Version 1

Abstract

-

The TASD 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.

The TASD file format is used for storing "Tool Assisted Speedrun" or "Tool Assisted Superplay" (TAS) input and configuration data for use with devices (known as "TAS replay devices") that replay inputs on physical video game 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.

This document defines the file format specification for TASD files.

1. Introduction

-

The Tool Assisted Speedrun Dump (TASD) 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 TASD 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.

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.

Packets of a given type can be used multiple times or completely omitted as needed. This reusability eliminates the need of a predefined delimiter to separate pieces of data.

-

While files generated by emulator dump scripts should provide as much information as possible, because packets are optional, the file can be expanded later with any additional data as desired. No intermediary file format is necessary.

    We use the terms Tool Assisted Speedrun, Tool Assisted Superplay and TAS interchangeably in this document.

    In subsections of (Section 4.2), the term "in direct form" is used. That term is defined to mean a packet in a TASD file directly (first order packet) rather than a packet inside a TRANSITION or MOVIE_TRANSITION packet (second order packet).

    String values MUST use UTF-8 encoding. As such, string values MAY contain any number of NUL characters and do not make use of "null termination".

    Variable-length integer encoding (also known as VarInt or VLQ) is not used in this format. Instead, arbitrarily sized integers, like those used in Section 4, are prefixed with a single octet that specifies the number of octets used to contain the integer value. In most cases, this is less space-efficient than VarInt encoding, but it is simpler to understand and to parse.

    TASD File Format Specification Version 1

    Abstract

    The TASD 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.

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.

    The Tool Assisted Speedrun Dump (TASD) 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 TASD 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.

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.

    Packets of a given type can be used multiple times or completely omitted as needed. This reusability eliminates the need of a predefined delimiter to separate pieces of data.

    While files generated by emulator dump scripts should provide as much information as possible, because packets are optional, the file can be expanded later with any additional data as desired. No intermediary file format is necessary.

    We use the terms Tool Assisted Speedrun, Tool Assisted Superplay and TAS interchangeably in this document.

    In subsections of (Section 4.2), the term "in direct form" is used. That term is defined to mean a packet in a TASD file directly (first order packet) rather than a packet inside a TRANSITION or MOVIE_TRANSITION packet (second order packet).

Not all content between quotations will be string value examples, so be aware of that when continuing through this document.

    String values MUST use UTF-8 encoding. As such, string values MAY contain any number of NUL characters and do not make use of "null termination".

    Both 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.

    Variable-length integer encoding (also known as VarInt or VLQ) is not used in this format. Instead, arbitrarily sized integers, like those used in Section 4, are prefixed with a single octet that specifies the number of octets used to contain the integer value. In most cases, this is less space-efficient than VarInt encoding, but it is simpler to understand and to parse.
