best. Frame advance and savestates are the most common way to quickly examine multiple attempts. Common results that rely on pseudo-randomly generated numbers in the context of video games include instances of artificial intelligence or the obtaining of random power-ups. Re-recording A feature in TAS-oriented emulators that allows movie recording to resume after loading a savestate, usually from a point in time before the current state in order to test other input sequences. ROM The read-only memory of a game cartridge dumped as a binary file on a separate file storage medium. It contains all data of a game cartridge, such as the programming as well as the graphics and music. Loading a ROM image of a game in an emulator is the usual method to play such games. Savestate A snapshot of the emulated system's state at that current moment. Restoring a saved savestate will revert the console and the game to that exact state, including the game's future outcomes of pseudo-random generators. This is known as a re-record when performed during the recording of a movie (input file). Slow motion The slowing down of an emulated system to make it easier to create input (thus increasing the potential precision). The usage of slow motion is crucial to tool-assisted speedrunning, as many of the esoteric techniques are impossible to perform without it due to mechanical and human limitations. Frame advance is the most accurate kind of slow motion. TAS Common abbreviation of tool-assisted speedrun. The word TAS is used in the tool-assisted speedrun community exactly like the word “speedrun” is used in the unassisted speedrun community. Since objectives of tool-assisted creations started deviating from only including fastest completions, the abbreviation is mutually used for tool-assisted superplay as well. Timeattack Tool-assisted speedruns are sometimes called "timeattack". This most likely stems from the Japanese term “タイムアタック” (“taimuatakku''”). In the English community, this term has mostly fallen out of favor; this term can also be seen in numerous games that have a lowest completion time mode (e.g. as opposed to "score-attack" mode, where the goal is highest score). See also Time attack — a mode which allows the player to finish a game (or a part of it) as fast as possible, saving record times. Score attack — the attempt to reach a record logged point value in a game. Electronic sports — video games that are played as competitive sports. Piano
