WeirdUtils

This package provides many pre-built DLLs for enhancing the vanilla 1.12 client WoW gameplay experience, aimed in particular at ease of use and accessibility but also bug fixes.

You may get all features by installing weirdutils.dll, or choose any selection of features via individual DLLs. On Turtle WoW, place your chosen DLLs next to your WoW.exe and add them to your dlls.txt. For other versions you will need some sort of DLL loader.

Features

PNG Screenshots

Saves screenshots as compressed PNG files instead of the default uncompressed TGA format. Runs on a background thread with no frame drops.

Controlled via the screenshotQuality CVar (saved to config.wtf):

• /script SetCVar("screenshotQuality", "6") -- set compression level (1 = fast, 9 = smallest, default 6)
• /script SetCVar("screenshotQuality", "0") -- disable PNG, use original TGA format

DLL: pngscreenshots.dll

---

Transmog Fix

Eliminates FPS drops caused by rapid equipment visual updates when transmogged items lose durability. No configuration needed, install and forget.

DLL: transmogfix.dll

---

Custom Data/ Assets

Enables loading loose game asset files (models, textures, etc.) from the Data/ directory without repacking MPQ archives. Place files in Data/ mirroring the game's internal paths (e.g. Data/Character/Troll/Female/TrollFemale.m2) and they will be used instead of the MPQ version.

Also allows multi-character patch archive names (e.g. patch-12.mpq, patch-jimbo.mpq).

Patch archives are sorted case-insensitively by filename - last in the sort gets highest priority, and all patches override the base archives.

No configuration needed, install and forget.

DLL: customassets.dll

---

Utility Minimap Trackings

Adds custom minimap icons for NPC types (vendors, trainers, innkeepers, etc.) and game objects (mailboxes).
Replaces the native tracking dropdown with a combined menu showing both spell tracking and NPC category tracking.
Can be disabled easily from normal AddOn menu.

• Click the minimap tracking icon to open the dropdown
• Check/uncheck NPC categories to toggle their minimap icons
• Spell tracking (Hunter tracking, Find Herbs, etc.) remains available alongside NPC tracking

Supports many NPC types such as Auctioneer, Banker, Flightmaster, Repair, Reagents, Poisons, and more
Supported game objects: Mailbox, Brainwasher

DLL: minimapicons.dll

---

Log Sessions

Organizes the combat, raw combat, and chat logs into per-character directories with timestamped filenames:

Logs\<Realm>\<Character>\WoWChatLog_YYYYMMDD_HHMMSS.txt
Logs\<Realm>\<Character>\WoWCombatLog_YYYYMMDD_HHMMSS.txt
Logs\<Realm>\<Character>\WoWRawCombatLog_YYYYMMDD_HHMMSS.txt (superwow only)

Every character login begins with a marker line (COMBATLOG_SESSION or CHAT_SESSION) identifying the character and realm. If a log file for the same character was written to within the last 60 minutes, the same logfile will be used instead of creating a new one.

Lua API for addon developers:

• GetCombatLogPath() -- returns the current combat log file path
• GetChatLogPath() -- returns the current chat log file path

No other configuration needed, install and forget.

DLL: logsessions.dll

---

SuperWoW Heal Text Fix

Fixes duplicate floating heal numbers caused by SuperWoW 1.5. Only relevant if you use SuperWoW. No configuration needed, install and forget.

DLL: healtextfix.dll

---

Big Cursor

Upscales the hardware cursor for improved visibility without losing sharpness. Supports fractional scales from 1.0 (off) to 4.0.

• /script SetCursorScale(1.2) -- set cursor scale (default 1.2x)
• /script SetCursorScale(1) -- disable (use original 32x32 cursor)

This value is saved to the cursorScale CVar in tenths: /script SetCVar("cursorScale", "15") for 1.5x.

Lua API for addon developers:

• SetCursorScale(n) -- set scale factor (1.0-4.0), takes effect on next cursor change
• GetCursorScale() -- returns current scale factor

DLL: bigcursor.dll

Why No Source Code?

This project is distributed as pre-built DLLs only. The source code is not and will not be made publicly available.

These DLLs work by hooking deeply into the game client's internals: memory layout, function addresses, rendering pipeline, input handling, and more.
While every feature here is built for legitimate quality-of-life use, the underlying techniques touch on too many core mechanisms that are trivially abusable.
Publishing the source would be handing a candy store to bad actors: the same hooks and patterns used to render a raid marker or fix a crash can be repurposed for cheats, exploits, and in particular automation with minimal effort.

Developer Notes

Runtime Module Control API

WeirdUtils exports three functions for querying and disabling modules at runtime in case other devs find their dll's in conflict.

Exported Functions

Function	Signature	Description
WeirdUtils_IsModuleActive	int __cdecl (const char *name)	Returns 1 if the module is compiled in and currently hooked, 0 otherwise
WeirdUtils_DisableModule	int __cdecl (const char *name)	Unhooks the named module. Returns 1 if found, 0 otherwise
WeirdUtils_DisableAll	int __cdecl (void)	Unhooks all modules and core hooks. Returns count of modules disabled

Module names are case-insensitive and match the build option names:

customassets, logsessions, transmogfix, minimapicons, healtextfix, bigcursor, pngscreenshots

The weirdutils_api.h header is included with each release.

There is no re-enable API - re-hooking after unhook is unsafe.

C/C++ Header

A header-only include/weirdutils_api.h is provided that handles DLL discovery and runtime resolution automatically. No .lib file needed:

#include "weirdutils_api.h"

// Returns 0 if WeirdUtils isn't loaded - safe to call unconditionally
if (WeirdUtils_IsModuleActive("transmogfix"))
    WeirdUtils_DisableModule("transmogfix");

The header tries all known DLL names (weirdutils.dll, pngscreenshots.dll, etc.) via GetModuleHandleA, so it works regardless of which DLL variant is loaded.

Raw GetProcAddress

If you prefer not to use the header:

HMODULE hMod = GetModuleHandleA("weirdutils.dll");
if (hMod) {
    typedef int (__cdecl *IsActiveFn)(const char *);
    IsActiveFn isActive = (IsActiveFn)GetProcAddress(hMod, "WeirdUtils_IsModuleActive");
    if (isActive && isActive("transmogfix")) {
        typedef int (__cdecl *DisableFn)(const char *);
        DisableFn disable = (DisableFn)GetProcAddress(hMod, "WeirdUtils_DisableModule");
        if (disable) disable("transmogfix");
    }
}

Module Mutexes

Each module also holds a named mutex while active: Local\WeirdUtils_<name>_<PID> (e.g. Local\WeirdUtils_transmogfix_12345). The exception is transmogfix, which uses Local\TransmogCoalesceHook_<PID> for legacy reasons.

If you see the mutex, the module is loaded - and can use the Runtime Module Control API to disable it. If you don't see it, the module isn't active and you're free to hook those functions yourself.
