What is a .ROA file?
An .ROA file is a special type of file that is used to save replays of matches from a video game called Rivals of Aether. Rivals of Aether is a popular fighting game that you can play on computers using Windows, and also on gaming consoles like the Xbox One and the Nintendo Switch. When you play a match in Rivals of Aether, everything that happens during the game, like the moves you make, the hits you take, and the outcomes of each round, can be recorded and saved into an .ROA file.
The information inside an .ROA file is saved in plain text, which means it's just regular written words and numbers that describe the actions and events of the game. This might include which characters were fighting, what moves they used, and how the match ended. Because it's in plain text, the file is not very big and doesn't take up much space on your computer or console.
When you want to watch a replay of a match you played or saved, Rivals of Aether can read the .ROA file and use the information inside it to recreate the entire match exactly as it happened. This lets you watch the match again, study your moves, learn from your mistakes, or just enjoy a particularly good fight.
To open an .ROA file, you need to have Rivals of Aether installed on your device. This is because the .ROA file is specifically designed for this game, and Rivals of Aether has the special ability to understand the text inside the file and turn it back into a replay of the match. Other programs won't know how to read the .ROA file correctly because it's made just for Rivals of Aether. So, if you have a replay saved as an .ROA file that you want to watch, just open Rivals of Aether, and you should be able to load and view the replay from within the game.
