What is Project Rio?

Project Rio is a modified version of Dolphin Emulator & a database developed by PeacockSlayer, LittleCoaks, & maybejon which serves two major purposes: automatically track & collect stats from in game, and optimize the experience of Mario Superstar Baseball, both online and offline. Project Rio also currently supports optimized online gameplay for Mario Golf: Toadstool Tour, with stat tracking and database support coming in the future. Our development discord can be found here!


Project Rio comes pre-built with gecko codes and configurations for different game modes, optimal default configurations for new Dolphin users, an automated Stat Tracker, which automatically records stats at the conclusion of games, and a web server where users can access a database of game stats.


Project Rio as a concept encompasses the entirety of the Mario Superstar Baseball Modding Project which began back in November of 2020, which refers to our massive plethora of Gecko Codes, this very website, and our future plans for the project. In the future, this website will allow users to sort through a database to view extensive & in-depth stats on a countless things in the game, such as but not limited to character stats and player stats.


The philosophy for this website's future is to act as a central hub for all things Mario Superstar Baseball related and detail the development of Project Rio. We plan to make many additions to this site, including but not limited to: information detailing game strategy, the metagame, community tier lists, community stats, and more.
