Street Fighter II' Hyper Fighting has become the fastest-selling Xbox Live Arcade title to date, Capcom announced on Friday.
The game achieved the feat over its first 24 hours on Xbox Live Arcade following release on August 2.
Capcom claims that "hundreds of matches" are taking place between online combatants every hour.
Information on sales of Xbox Live Arcade games is slightly inconsistent. At the turn of the year, Microsoft announced that Geometry Wars: Retro Evolved had been downloaded more than 200,000 times and bought more than 45,000 times.
In June, it subsequently revealed that UNO had the highest daily demo-to-sale conversion rate - between 40 and 45 percent - having eclipsed Geometry Wars' 39 percent rate.
It would easy to infer from the companies' careful use of unrelated stats that Street Fighter II's record is not as impressive as either of those two titles yet. However, it's safe to say that it marks SFII out as the most successful Xbox Live Arcade Wednesdays title to date.
Previous Wednesdays games were Frogger, Cloning Clyde and Galaga. Pac-Man is due to appear on Live Arcade this Wednesday at 8am GMT.
Street Fighter II' Hyper Fighting costs 800 Microsoft points, or GBP 6.80, with a trial version also available.
