Very simple GUI tool here - you can use it to convert any unlicensed team in .bin files (Team.bin or Team4.bin) to licensed and vice-versa. Nothing more, nothing less.
Simple File > Open, (un)license any teams you need, File > Save. Multiple teams can be selected at once. All you need as prerequisites are already extracted Team.bin and/or Team4.bin files - either zlibbed or unzlibbed.
Nothing fancy about it, there are other tools capable of doing the same thing, but at least two of them are much harder to set-up if you only need quick licensing/unlicensing of several teams in db files - e.g. Kit Studio and DinoTem editor.
Feb. 5th, 2020 - new simple tool to (un)licence competitions added to the collection, which now goes under new name - Simple Tools. Newly added Competition Licencer functions in pretty much the same fashion as Team Licencer does - File > Open, (un)license any competitions you need, File > Save. Multiple competitions can be selected at once. All you need as prerequisites are already extracted Competition.bin and/or Competition4.bin files - either zlibbed or unzlibbed.
