and posted on the site alongside the runner's comments, which can detail specifics regarding the run. Rules Fundamentals Submitted speedruns are typically performed on their native consoles. When performing a run of a PC game, the rules may mandate that certain computer configurations be adhered to. In general, SDA will not accept runs that are performed on emulators, as emulation can be influenced by the configuration of the computer being used. Furthermore, it is particularly difficult to verify whether or not a run performed on an emulator is tool-assisted. Nevertheless, SDA does permit the use of emulators in certain cases; submissions performed on the Game Boy Player, GameTap, and Virtual Console are allowed. Virtual machines and DOSBox are allowed in cases where an older PC game does not run properly on modern computers. Use of this software is reserved for specific circumstances and these submissions must adhere to several additional rules. Due to potential emulation inaccuracies, runs that utilize an emulator may be categorized separately from those of the original release. Non-cosmetic modifications to a game, console, or controller are not allowed. Glitches that are triggered by interfering with the normal operation of the hardware or game media while the game is running, such as the crooked cartridge trick are not permitted. In-game glitches or exploits may be permissible, contingent on the category being run. It is required that runs be recorded using direct-feed capture. This is typically done using a capture card or DVD recorder. A run may be rejected if the quality of the recording is insufficient. Segmentation Segmented Utilizing the in-game save system, the run is performed in multiple parts. Segmented runs allow the player to retry each individual section of the game as many times as they desire. As a result, fully segmented submissions are heavily scrutinized and held to a higher standard of gameplay than single-segment runs. Single-segment The entire game is beaten from start to finish in a single sitting. Excluding situations in which doing so is necessary to continue the game, the player may not utilize either soft or hard resets. Single-segment with resets (also known as real-time attack) A single-segment run that permits resetting the game. Not every game is eligible for this form of segmentation; it is typically only utilized when the use of resets saves a substantial amount of time. Completion SDA accepts runs that adhere to one of three
