During my research I found this Old advertissemnt :
And I think those games have no DNAS. So this doesn't mean we can now play those games as they all used their porper server (later games went to gamespy server). But may be someone could try to recreate them and everybody could play those games
In the list we have (all titles are NTSC-U):
- Automodelista (no DNS)
- ATV Offroad Fury 2 (no DNS)
- Madden NFL 2003 (no DNS)
- Tony hawk Pro Skater 4 (DNS : 24.104.236.98 )
- SOCOM US Navy Seals (no DNS)
- Frequency (no DNS)
- Twisted Metal Balck online (DNS : 173.198.252.240)
- NFL gameday 2003 (no DNS)
- Tribes Aerial Assault (DNS : 142.4.223.231 or DNS : 24.104.236.98)
If you know about other games with no DNAS just post it here.
