BrawlStats is a Wii application that will have to be run after a Super Smash Bros. Brawl session. It will store automatically on your SD your results and then you will be able to navigate freely through a clean GUI that will show you a lot of information that Brawl doesn’t store (or doesn’t show). It also gives different trophies to players that achieve certain records. It can be like a database of your Brawl matches.

IMPORTANT NOTE: If you are updating from older betas you must move your .bss files from sd:/brawlstats to sd:/config/brawlstats and also copy the new meta.xml overwriting the old one.

Watch this video on YouTube.

Changes:

warns user if a session was not created correctly (due to a corrupted SD card, for example)
shows a loading bar when reading sessions from SD
