I have received many messages about the compatibility of No Borders and version 21.4
No borders 21 is compatible with all versions of the FM21
Compatible with all versions of FM 2021.
Using this database you can play in any league in Europe and be able to sign unlimited players of any nationality. No need for work permits and no limits for foreign players.
Playing on other continents, clubs will receive many transfer offers as European clubs will be able to sign players without limits from all over the world.
This doesn't affect any continental competitions nor the nationalities of the players, just adds all countries in the EU.
Fix 1.1 Serbia included
Fix1.2
Albania included
Montenegro included
North Macedonia included
Bosnia-Herzegovina included
How to install the Sin Fronteras database on FM21
1) Move the downloaded .fmf file to your editor data folder (create that folder if it doesn't exist):Windows \Documents\Sports Interactive\Football Manager 2021\editor data
Mac Users/YOUR Mac USERNAME/Library/Application Support/Sports Interactive/Football Manager 2021/editor data
3) Start new game in regular career mode (doesn't work with FMT/FMC) and activate the No Borders - Sin Fronteras 21 database (is compatible with other databases).

They are rules of Serbian competitions.
I have never played in Serbia. I don't know the rules of that country.
You should edit the rules of Serbian competitions.
If I know the rules of Italy I suppose they must be similar.
The pre-game editor doesn't work very well, but it would help you to be able to change those rules.
You have to start a new game with No Borders 1.1.
What league or country are you playing in?
In Italy for example they have rules with foreigners and not with community people.
I already have it in my workshop.
It has not yet been approved in FMScout

In version 1.0 Serbia is included 07/01/2027.
In version 1.1 Serbia is included from the beginning.
I recommend waiting for a No Brexit database or similar once the pre-game editor works well.
In that case, when you create a game, you will be able to select No borders and no Brexit without compatibility problems.
It is not possible to modify rules in England due to errors in the pre game Editor, the people of SI are fixing it.
Playing in a European league, English players are going to be taken as community.
Simulate the game until after 11/26, which is when the limitations begin and all players with English nationality are taken as community members, for example playing in Spain and buying an English player, there would be no problem. He takes it as a community.
Buying players outside the UK, playing with an English club for example Manchester United, it allowed me normally, without restrictions.
The rules for the English leagues, the Editor-Pre-Game does not work correctly.
It is under review, when it is corrected it will be possible to modify the league, not only the English one, but it is almost the majority of the entire world.
No Borders, it works fine.
For DB No Brexit, there are some on Steam, but I do not recommend using them at the moment they could generate future errors in the games.
