Starcraft ladder

OK thank you very much,

That's what I'm doing for the moment

ladder_games = "topvbot, oneonone"
ladder_prefix = "ldr_"

In previous versions of starcraft, when you created a ladder game if you chose a non-ladder map pvpgn said it was not a valid map,

Is this checking server-side or client-side?

Ladder maps have an icon that characterizes them, there is a way to create these maps ?, ie "sign them with these icons", I remember that if I edited the map Lost Temple (for example), it lost the icon and was no longer valid for a ladder match.

Thank you very much

Other questions

I already managed to make the starcraft work in league mode with the leaguedevkit provided here harpywar.com/?a=articles&b=2 … mp;lang=en, create the mpq and sign it with the MPQSigner, so that I no longer need the approval and works perfectly.
When creating the mpq you have to include several * .pcx, one of them is map.pcx which is for the official maps of the league.
Another is admin.pcx for league administrators.
Someone worked with the leaguedevkit, there is more documentation on the subject, how can I make the map official in the league, and how are league administrators created?
Sorry for asking so many questions, thanks again
