UniDB definitely does not convert the .db to Microsoft Access, its version must be the conventional one that is adaptable only to Fifa14.Sadly not, I tried to open the db with unidb and it just froze
We need much more than that to modify the database. Maybe using tools from the Fifa PC versions like CM and others will work...
As for the uniforms in the game. Rx3Master solves the problems of modifying any Kit, importing/exporting the texture easily, what is bad is the COLORS, there is a strange inversion that is necessary to find for each specific color of the PNG edition.
Currently... I only have problems with some teams like QueensPark Rngrs (Id: 15) or the Real Zaragoza (Id:244), their ID-Teams don't seem to change in Fifa16. Opening the database, maybe we can find the correct ID for the teams that don't change uniforms.
