+/*
+This is the source code for the lobby_connect.exe program.
+If you want to build it, just dl the steam sdk and link it to the steam api dll
+Then to execute it just use my emu dll instead of the steam sdk dll.
+
+If you make any improvements and want to share them post your code in the thread and if it improves it I'll use it.
+
+You can also use this code to add this functionality to your launchers.
+
+Note if you use my steam emu dll: When I build my lobby_connect.exe I static link it to a build of my emu that has reading from disk disabled.
+This means that it's a good idea for you to use local_save.txt so that your launcher doesn't conflict with running
+games by having the same steam user id. There must also be no steam_appid.txt or else you will only see games with that appid.
