wow for real? where i can find this shirt?
i didn't know about other FIFAs leftover, thanks for explain!
Yes, in the database there is a "league" called "Street Video - Temp", which is ofcourse not accessible in game, where (presumably) EA had the teams they used in trailers/intro. Those teams are still in the database and one of those teams in the database is called "Messi Street Video Team", which is pretty self explainatory and is the team Messi plays in in the trailer. They use top type = 10 and top texture = 5, so in the game files you find the FIFA Street clothes in data7.big (data/sceneassets/clothes), therefore the file you need is top_10_5_cm.rx3, which contains the textures (kit texture + mask).
Now keep in mind, the FIFA Street clothes textures are all in Red/Green/Blue colors, since the game recolors those parts based on the RGB color codes of the team's kitcolors in the database (so for example if this top was assgined to Arsenal's home kit, the red colors of the kit would be the primary color of Arsenal's kit (red), the green color would be the secondary color of Arsenal's kit (white) and the blue color would be the tertiary color of Arsenal's kit (black for example)). That is how it works in the game FIFA Street.
You can also recolor them yourself with some basic "photoshop" skills (like using Paint.NET).
could you make a mod for that? to make it accesible?
