The Future is NOW
Can't wait to get your hands on Source Media Arcade 2? Then don't wait. A fully functional release candidate is now publicly available in the Downloads section.
This early-release version contains the original 2 maps and over 20 dynamic arcade cabinet models to start you off with. Remember that SM Arcade can use all of your favorite Source engine maps! Just drop them into your "smarcade2_rc1/maps" folder and they'll appear on the map list. Stock maps can be loaded with the console command "map de_dust2".
RC1 is basically a finished version of the mod. It is only missing the all-new maps and cabinets that are to be packaged with the official release come Halloween.
You have the green light to start importing your media collections.
Your media library and custom built arcades will be fully compatible with the official release come Halloween, so don't worry about losing your creations. Upgrading will be as easy as copying a few files and folders over.
If you need any help at all, just visit the official ModDB forums and start a new question thread. If necessary, I will make demonstration videos to show you exactly how to accomplish what you are trying to do.
Note: "Singleplayer" mode is when you Create Server with Max Players set to 1.
Also Note: There are no dedicated servers for Source Media Arcade. All servers are peer-hosted by other Source Media Arcade players. When your friends join your multiplayer server, they will potentially see your arcade EXACTLY as you do.
