Samapico

This is a tool that can help convert a zone with a lot of arenas from subgame to ASSS.
 
You give it a folder with all the lvl, cfg and lvz files of your subgame server, and an empty folder that would be your ASSS root, and it will copy the files properly in a ASSS folder structure.
It is not recommended to specify a real ASSS root folder, since some of your files could be overwritten. Use an empty folder, and the program will create folders named 'arenas' and 'maps' in it. 'arenas' will contain all of your arenas, while 'maps' will contain all the lvz files.
 
Example of arena.conf file created by this tool:

#include conf/svs/svs.conf #include conf/17th/default.conf #include #mist.cfg [ General ] Map = #mist.lvl LevelFiles = [ Misc ] SeeEnergy = $SEE_TEAM SpecSeeEnergy = $SEE_ALL [ Modules ] ; this key holds the names of the modules that will take effect in this ; arena. typical things to put here are modules for scoring, special ; game types, flag guards, etc. AttachModules = \ fm_normal \ points_kill \ points_flag \ points_goal \ buy
 
Note that this will only convert arenas themselves, and does not deal with server settings (i.e. server.ini). Flag settings and other particular things that require specific modules are not guaranteed to be ported properly.
