FyreChat

FyreChat is a binary chat application developed from FyReBoT source. It connects to Battle.net — the online service behind classic Blizzard games like StarCraft, Diablo II, and WarCraft III — by speaking the games’ own network protocol, so the server sees it as a real Blizzard game client. That means full chat channels, commands, and account management without ever launching (or even installing) a game.

Does it still work? (tested July 2026)

Yes — logged into live uswest.battle.net in 2026. What connects depends on whether Blizzard remastered the game:

✅ Official Battle.net — Diablo, Diablo Shareware, Diablo II + LoD, and WarCraft II: BNE (with a valid CD key). Diablo II needs a BNLS server that supports Blizzard’s 2019 “CheckRevision 3a” scheme.

❌ Blocked on official — StarCraft, Brood War, WarCraft III + Frozen Throne: remaster-era changes (2017/2018) killed the classic logon. These work on a PvPGN server instead (verified on Diablo II) — WarCraft III also needs a small source change to skip PvPGN’s server-signature check.

BNLS server: the old bnls.net default is gone — point FyreChat at a community one: bnls.openfyre.net:9367, jbls.davnit.net, or run your own.

FyreChat logging into the official uswest.battle.net as a Diablo II client — account auto-created and entered chat — July 2026.

Supported Clients

FyreChat can log on as any of these classic Blizzard clients. Most require a valid CD key for the game; Diablo, the shareware clients, and Japanese StarCraft use the old logon and need no key:

Icon	Client	Icon	Client
	StarCraft		StarCraft: Brood War

	Diablo		Diablo Shareware
	Diablo II		Diablo II: Lord of Destruction
	WarCraft II: Battle.net Edition		WarCraft III: Reign of Chaos

Plugins

FyreChat supports BCP (BinaryChat Plugin) plugins — Skywing’s shared plugin format, loaded through BCEL.dll and also used by compatible bots like SphtBotv3. The following is a list of recommended plugins.

oper.dll [ Documentation ] By Spht

Aliases.bcp By Yoni
- Allows you to create your own aliases for commands, or create chat-shortcut commands.
AlwaysOnTop.bcp By Spht
- This plugins creates a “Window” menu from which you can toggle the bot being displayed on top of other windows at all times, even when it loses focus.
Trivia.zip By Spht
- Loads trivia questions and keeps track of user scores. /trivia on|off|auto.
WinampControl.bcp By UserLoser
- Allows you to control Winamp through the bot. Commands: /play, /stop, /pause, /next, /back, /sop, /eop, /volup, /voldown, /rewind, /forward, /closewinamp, /songinfo, /sendsonginfo.

More Plugins

BNLS/JBLS Server

BNLS (Battle.net Logon Server) handles the version-check and password-hashing steps of logon so the bot doesn’t need the game files installed.

Public server (easiest): set FyreChat’s BNLS host to bnls.openfyre.net (or jbls.openfyre.net), port 9367. It’s a hosted JBLS instance I keep current — including the CheckRevision 3a support that fixes Diablo II logon on official Battle.net (the classic 2007 build below can’t do this).

Run your own: build from Davnit/JBLS — the maintained source, which includes the CheckRevision 3a support Diablo II needs. (jbls.davnit.net runs it too, as another public option.)
