Hey everyone who still plays GTA1 or is interested in playing GTA1 online. I write a client and server called GTADS that allows you to find players and set up multiplayer without having to know IP addresses or opening up multiple ports. There is a lot of work to be done with it to make it "complete" but it allows you to get back into the classics and play a fun deathmatch game. I plan to extend support for GTA2 and a slew of other games that aren't "easily" played over the internet with random people.

You can look for me in there as either sday or admin.
Please note, a new version with more features coded is slated for the end of this week.
Enjoy,
