[CS1.6] HLTV is not listed in the master server

[Splatt581]

It seems that the problem concerns only CS 1.6, because if we look in the “Speсtate” tab in the server browser, for example, for the game Сondition Zero or Half-Life, we will get several working HLTVs. For CS 1.6, this tab is empty, but this does not mean that no one has HLTV running, I myself host a HLTV server and it is not displayed in the master server.

@shawns-valve HLTV not listable for Counter-Strike in master server, because HLTV sends version 1.1.2.6 to the master server, but CS 1.6 requires at least version 1.1.2.7. This can be checked by steamapi endpoint:

https://api.steampowered.com/ISteamApps/UpToDateCheck/v1/?appid=10&version=1126&format=xml

This can be fixed inside the Master::RunFrame function:

void __usercall Master::RunFrame(int a1@<eax>)
{
...
(unsigned __int8)SteamGameServer_Init(_byteswap_ulong(*(_DWORD *)(v44 + 4)), 0, 0, 0xFFFF, 1, "1.1.2.6")
...
}

Just change version 1.1.2.6 to 1.1.2.7 and the problem will be solved.
