On December 7th 2012, GameSpy stopped providing services to Halo Trial. This meant that when you clicked "Get List" you would be returned no servers making it impossible to play Halo Trial multiplayer unless you knew the IP address of a server.
But don't panic! Thanks to Tavrin there is now a fix.
Tavrin has made his own master server which is able to take over from the GameSpy server. This means we need to patch our halos to make them use Tavrins master server to get the list of multiplayer games from.
You will need to get this new patch even if you already have TrialGSFix.dll because TrialGSFix.dll still uses the GameSpy server which means it will stop working once GameSpy fully stops their services. Tavrins master server will also let you see the pings of each server and servers without the patch can be manually added. All of the Ratxxxx InJapan servers have been manually added so you will be able to see them in the list even though they don't have the patch. This is why it is very beneficial to get this new patch.
Downloading and using the patch is very easy. Please see the simple instructions below.
Please be aware that both clients and hosts MUST have this patch. Clients with this patch will only be able to see servers which also have this patch.
You can help by telling everyone you know about this patch so that we can get Halo Trial back up and running to how it was before.
Keep checking this page, as I will be updating it with any new information.
