port-a-mod

rehan-remade/un…l-modder

Port an existing mod to a newer game version or another mod loader while keeping its behaviour, values and quirks. Typical cases are an old Forge 1.7.10 or 1.12 Minecraft mod moving to modern Fabric or NeoForge, a Skyrim LE plugin moving to SE/AE, or a tModLoader 1.3 mod moving to 1.4. It covers pinning one source version, a private decompiled reference, an adaptation matrix, extracting the mod's data with scripts instead of retyping it, porting unit by unit with tests that catch drift, real-client checks, audits against the original, and keeping a long port resumable across sessions and agents. Use when the user wants to update, port, revive or re-implement a mod that already exists, or to continue such a port.

Port a mod faithfully

When porting an existing mod, the original is the spec. A port rarely fails for lack of code. It fails by drift:

  • values recalled from memory or a wiki;
  • mechanics borrowed from a later rewrite of the same mod;
  • quiet "improvements";
  • renderers that look roughly right;
  • checks that the original made on the client and the port forgot.

The method below carried a Thaumcraft 4.2.3.5 port from Minecraft 1.7.10 Forge to 1.20.1 Fabric:

  • 859 original classes became about 77,000 lines of port code;
  • 323 GameTests cover it, and scripted real-client scenarios check what tests can't reach;
  • the work spanned many sessions and two agent accounts.

The field note knowledge/games/minecraft/porting-thaumcraft-4-1-7-10-forge-to-minecraft-1-20-1-fabric.md has its gotchas. Minecraft-specific mappings are in references/minecraft-1-7-10-forge-to-1-20-fabric.md.

mod-any-gamerehan-remade/un…l-modderMod a PC game the user owns, taking an idea to working in the real game and recorded. It covers new items, weapons, enemies, bosses, units, civilizations, mechanics, art, sound, VR and cross-game mashups. Use when the user wants to mod, extend, hack on, reverse engineer or mash up a game ("add a nuke to Terraria", "make a new civ for Age of Empires", "put Minecraft inside X", "can I mod this game?"). It covers recon (engine, loaders, anti-cheat), choosing the route, a safe lab, a first vertical slice, fal-generated assets, in-game verification and a showcase clip.设计与多媒体1690reverse-engineeringrehan-remade/un…l-modderRead how a game actually works so a mod can hook it. Decompile .NET/Mono (ILSpy), IL2CPP (Cpp2IL, Il2CppDumper), Java (Vineflower) and native code (Ghidra, IDA, via MCP servers); dump data and asset formats; reverse-engineer a binary file format and prove it with a round trip; read live memory (Cheat Engine, Frida, x64dbg); find render passes (RenderDoc). Use when a mod needs game internals, e.g. "how does the boss AI work", "find the damage function", "what format is this .sld/.pak/.dat", "where is the player position in memory".智能体工作流1681game-reconrehan-remade/un…l-modderFigure out how a specific installed game can be modded, before writing any mod code. Covers where it's installed, the engine and version, managed vs native code, anti-cheat, loaders already present, save and config folders, and the community's modding route. Also whether this machine can run it (a Windows game on macOS or Linux, x64 on ARM). Use when the user asks "can I mod <game>?", "what engine is <game>", "how do people mod <game>", or at the start of any modding task. Produces MODDING_PLAN.md.智能体工作流1646game-automationrehan-remade/un…l-modderLaunch, see and drive a real game so an agent can test its own mods. Covers launching via Steam or the exe, windowed mode at a fixed size, screenshots of the game window (GPU-safe capture), clicking and typing into menus, holding keys, relative mouse, crash-reporter cleanup, killing by PID, reading logs, scripted test scenes, and an in-game JSON bridge that lets an agent observe and act. Windows-first (also from WSL), with notes for Linux and macOS. Use when a mod must be verified in game, when navigating menus automatically, or when building a repeatable test or demo scene.测试与安全1593mashup-modsrehan-remade/un…l-modderBuild cross-game mashups and total conversions, the "Minecraft inside Elden Ring" or "skateboarding in MW2" kind. Covers passthrough mods (two games running at once and exchanging state, rendering and collision), porting one game's content or mechanics into another, embedding a decompiled game as a library, and clean reimplementations that read the user's own game files. Use when the user wants to combine two games, bring an enemy, mechanic or world from one game into another, or rebuild a game's runtime, or reimplement the guest's rules headless inside a real host.营销与写作1585asset-pipelinerehan-remade/un…l-modderTurn generated or hand-made art into exactly what a game engine loads. Covers sprite cutout, trim and nearest-neighbour fitting to frame sizes, pixelation to a palette, sprite sheets and strips, player/team-colour masks, seamless textures, and rendering a 3D model into sprite frames from the game's own camera (isometric/RTS 8 or 16 headings, side view, top-down) with Blender. Use after generating assets, or when the user asks to make sprites, sprite sheets, animation frames, isometric unit sprites or icons for a game.设计与多媒体1577
