BTM Pro (Net+) since version v29.00 is portable. That means that you don't have to install it, you can save it to any folder on disk including removable media such as USB memory and can run from that location. Eventually, you can create desktop shortcut.
For a game you only need file "BTMPro.exe", keeping the folders "Decks" and "Background" depends on you.
I recommend that ALL network players use the latest version, older versions were sometimes buggy.

BTM Decks v6.00 or later is a set of decks in folder "Decks" for BTM Pro (Net+) version v10.00 or later. Current decks contain 10 additional decks and 5 custom decks that you can define by yourself. You are permitted to modify decks, to make your custom decks, but don't use "BTM Decks" name as a product name. You can also publish your decks, but don't sell them. If you add or modify images be aware of:
- do not rename folders and files
- set the mask images properly (file "mv.gif")
- individual card image height must be up to 279 pixels, width must be up to 151 pixels
- each card is centered on background with border (file "bd.jpg")

Users of BTM or Yamb could have an issue about making connections when playing over a network. Basic thing is that you have to configure firewalls and other filters to not to block connections. There is a big difference when playing between LAN and Internet.
When playing over company or home LAN usually there shouldn't have been any of issues. Commonly you can forget playing over Internet in a company. Home users can have an issue making these games running as TCP servers over Internet. To make easier this, BTM and Yamb use UPnP port mapping. If you can't make BTM or Yamb acting as a TCP server, maybe other players whom you play with can do that, there is a need for only one player that can do that.

Q: How can I configure my router?
A: By accessing to router's application from any web browser, you have to know LAN internal address of a router.

Q: How can I enable UPnP on my router?
A: In order UPnP port mapping to work, your router has to be UPnP capable and enabled. If it is not UPnP enabled by default you can enable it through router's application. Be aware that enabling UPnP can be a security risk, if you are not advanced computer user, better skip that.

Q: How to configure port forwarding on a router?
A: You can do that if UPnP port mapping fails. That is done only once on a router for a particular game. You should also open that port for listening in that game.

Q: How to manually open a port for listening in BTM or Yamb?
A: When you tick 'This computer is a server', untick 'Automatic' and enter a port number.

Q: How to find external IP address if BTM or Yamb fails to find?
A: Web sites such as whatismyip.com can let you know which is your external IP address. If you are behind a router, also router's application should tell you that.

Games BTM Pro and Yap Yamb use HTTP Game Server, on which you can connect without logging in, playing private games with your friends or public games with players only from your country.
Direct network playing via IP addresses is much faster then Game Server. Main advantage of Game Server are public games, and playing is much easier to configure, since there are only outgoing requests which you allow on firewall. Sometimes it is necessary for me to deny access to Game Server from older versions of these games because of synchronization, bugs or improvements. Then you could download the newest version of game.
