Hello, I am Kevin Masterson. At various points in my career, I have worn the hats of software developer, network engineer, and system administrator.

I am originally from the United States, but I currently live in Bulgaria with my wife and our dog.

My long-time personal project has been QMM (Quake3 MultiMod). It is a dynamic plugin manager for games based on the Quake 3 engine (and now also the Quake 2 engine!). It functions similar to Metamod for Half-Life and Metamod:Source for the Source engine (Half-Life 2).

I began writing it while at University of Maryland in 2004, and the code was originally hosted on SourceForge while the main site was hosted on PlanetQuake.

Eventually, I stopped working on it, and only did anything related to it when a few people emailed me. In 2015, long after PlanetQuake disappeared and SourceForge went downhill, I made repos here on GitHub, but otherwise left them untouched. I have since (Mar 2025) begun working on QMM (and various plugins) again.

Take a look at some of the QMM-related repos:

• QMM2 - The main plugin manager (how it works).
• qvmops - A simple CLI QVM disassembler with code and data segments and support for reading symbol information from .map files.
• RocketMod_QMM - A simple "Rocket Launcher-only" game mode plugin for Quake 2 and Quake 3 Arena.
• Stripper_QMM - Plugin that dynamically modifies map entities during loading -- similar to Half-Life's Stripper2 and Stripper:Source for Source engine games.
• QAdmin_QMM - Plugin to administer servers with in-game commands and access levels.
• AdvChat_QMM - A plugin that allows for predefined variable replacement in chat, like $h for health or $a for armor.
• Stub_QMM - A basic sample trace plugin that outputs every message and some commonly-used arguments.

Take a look at some of my other projects:

• ipredir - outgoing IP redirection+NAT for Windows.
• FRSScan - Flipper Zero app to scan FRS channels for activity.
• SteelSeriesGG Helper - Simple script to reset settings in the Sonar section of the SteelSeries GG app.
• QuestNoise - World of Warcraft addon that plays a sound when you have made objective progress, completed an objective, or completed a quest.
• HideHotKeys - World of Warcraft addon that allows you to hide button text showing the keybind and/or macro name.
• FlightWarn - World of Warcraft addon that plays a warning sound when you have flown in a straight line for too long, or if you have flown into fatigue. Useful for alt-tab flying prior to Dragonflight.
• wowaddons - Other World of Warcraft addons that are older and not as popular to maintain anymore.
• WeapTFC - Plugin for Half-Life Metamod to provide AdminMod scripts with callbacks for certain events. Also includes an AdminMod script to utilize these functions.
• w48crash - Original PoC for CVE-2007-1260, discovered by me.
• WriteELF - Tool to place a Wii homebrew ELF file onto an SD card at a certain sector. Used in conjunction with the original "Team Twiizers" savegame hack for The Legend of Zelda: Twilight Princess.
• VoxelMapRedir - Hook DLL and DLL injector for an old version of Minecraft's VoxelMap plugin. It hooked Windows kernel32.dll function calls to fix path lookups when playing on a Minecraft Realm.
• aimpatch - Proxy DLL for the old AIM 7.5 client to remove a giant ad at the bottom of the window.
