Essential improvements
This game is best experience with ScummVM.
Multiplayer
The game has options for two-player gaming using either a serial null-modem, or a regular serial modem.
To use the null-modem option a non-standard null-modem cable is required, that is documented in the games manual.
Use DOSBox-X[citation needed] |
---|
When run in DOSBox-X, it is possible to use the serial modem emulation to setup a two-player game. While DOSBox-X also supports null-modem emulation, it is incompatible with the cable type required by the game. It is necessary to setup and start one game in "server" mode and the other in "client" mode. On the "Mission Selection" screen, both players must select the same mission to play, and one player needs to select blue and the other red. Only missions with a thunder-bolt are supported for multi-player. On the "Configuration Panel" screen, both players must ensure that "MODEM ON COM1:" is selected. Then the player with the Server config must select "AUTO-ANSWER" and wait for the client to connect. The player with the client config must ensure that the "SET TELEPHONE NUMBER" is set to "1", and click "ORIGINATE" Server Setup - DOSBox-X config The person that will run in server mode needs to configure his DOSBox-X with the following settings: [dosbox] title=688 Attack Sub - Server [cpu] core=normal [serial] serial1 = modem listenport:12345 rxdelay:50 [autoexec] mount c . c: loadfix /a 688.bat Client Setup - DOSBox-X config The person that will run in client mode needs to configure his DOSBox-X with the following settings: [dosbox] title=688 Attack Sub - Client [cpu] core=normal [serial] serial1 = modem rxdelay:50 phonebookfile = ./local.txt [autoexec] mount c . c: loadfix /a 688.bat Client Setup - phonebook file Please create a file named "local.txt" with the following content: 1 localhost:12345 Replace "localhost" in the above phonebook file example with the IP address or hostname of the player running the server config. |
