it has both sizes, Vialli recommended this editor's work, and I liked it a lot, too.
most Liga MX clubs have rather small squads right now (24-28 players), so the fake players from PLA probably sufficed, considering that some licensed players were in the game already. I checked the fake teams in other American section, all their players are still there, so there shouldn't be any compatibility issues on Petriz's end. From what i understand the guy is an advanced master, so I suspect he used computer tools to add new players with new ID if it was necessary, no created players certainly.
For Libertadores, Sepulveda's compilation was very good last year. They used created players (not many), so again, there were no conflicts with other leagues. Their v1 is out, but I am waiting for V2 for fixes and a bunch of extra stuff, so I haven't used the current one yet.
