Multiplayer in this game was never meant to run over the internet, so if you're playing with people outside of the local network it's likely the latency is too high and it's waiting for transfer between ticks. I've played LAN games over the dosbox ipx emulation without running into problems. The multiplayer was also only added in a patch so it was in many ways an after thought, though it is very fun.

You could try using hamachi, it creates a virtual local lan between computers via the internet.

im trying to run the game over wireless lan so im afraid hamachi won't work here, cat find a good solution online ether so im hoping for someone to come with a good awnser.
