Right now only MTA:SA is supported, but GTA3:MTA and MTA:VC aren't able to list, despite a news announcement saying otherwise. Any chance this could be fixed, please?
The version of the server application currently would be 0.5 and its related variants, which all work the same way. The games supported by this version are Grand Theft Auto III and Grand Theft Auto: Vice City, (whereas MTA:SA supports just Grand Theft Auto: San Andreas).
The only difference in ports is that the default port for GTA3:MTA and MTA:VC is 2003, with the query port of 2126. MTA:SA's, as many know already, is 22003, with a query port of 22126. It is really just a matter of adding an extra number there.
