MamboDMA — Multi-Game DMA Overlay & Tools (C# / .NET)

This project provides a pluggable DMA overlay framework built with:

• DMA/VMM backend via VmmSharpEx

• Raylib-cs + ImGui.NET (via rlImGui) for rendering

• JobSystem for threaded background work

• Config & Snapshot system for per-game persistence and fast UI updates

• Game plugin architecture (IGame, GameRegistry, GameSelector)

• SVG/PNG assets loader (logos, icons)

Everything runs out of the box, the UI is dockable, and the service layer is designed for adding new games and overlays.

Features

• Register any number of game plugins (DayZ, Reforger, Example, etc.)

• Switch active game via dropdown (GameSelector)

• Per-game workers (attach, entity updates, ESP drawing)

• Service panels for VMM control, process attach, modules, display settings

• Input manager & Makcu device support

• SVG/PNG logo support with crisp scaling

• Config persistence in %AppData%\MamboDMA

---

Screens

• Home: Select game, attach VMM, processes, modules

• Game Panels: Per-game UI (ESP toggles, debug windows, workers)

• Top Info Bar: Logo + title + FPS + resolution + close button

• Service Control: VMM init/dispose, attach, input manager

Project layout

MamboDMA/

Program.cs // entry point (UI mode selection + GameRegistry setup)

OverlayWindow.cs // Raylib + rlImGui init, ImGui fonts, dockspace

Games/

IGame.cs // plugin contract

GameRegistry.cs // register/select/stop active game

GameSelector.cs // UI dropdown, top bar, service panels

GameHost.cs // thin glue to tick/draw the active game

DayZ/DayZGame.cs // full example plugin with updater & ESP

Reforger/ReforgerGame.cs

Example/ExampleGame.cs

Services/

JobSystem.cs // thread pool + cancellation

VmmService.cs // VMM lifecycle + snapshots

Snapshots.cs // app-wide snapshot state

Gui/

Assets.cs // load PNGs to Texture2D

SvgLoader.cs // rasterize SVG → Texture2D (SkiaSharp)

Misc.cs // helpers (monitor selection, etc.)

StyleConfig.cs // ImGui theme persistence

Requirements

• Windows 10/11

• .NET 9 SDK

• VmmSharpEx runtime (DMA device attached, e.g., fpga)

• GPU with raylib/DX11

• Fonts: Assets/Fonts/AlanSans-*.ttf

---

Build & run

dotnet  build  -c  Release

dotnet  run  -c  Release

On launch, you choose the UI mode:

Choose UI:

[1] OverlayUI (Advanced)

[2] ServiceDemoUI (Simple)

[3] Game UI (with game selector)

Pick 3 for multi-game mode.

---

Game plugins

Each game implements IGame:

public  sealed  class  MyGame : IGame {

public  string  Name => "MyGame";

public  void  Initialize() { /* one-time setup */ }

public  void  Start() { /* spin up JobSystem workers */ }

public  void  Stop() { /* stop workers */ }

public  void  Tick() { /* lightweight per-frame logic */ }

public  void  Draw(ImGuiWindowFlags  flags) {

// ImGui controls, ESP overlays, debug windows

}

}

Register in Program.cs:

GameRegistry.Register(new  DayZGame());

GameRegistry.Register(new  ReforgerGame());

GameRegistry.Register(new  MyGame());

Select from UI → Game combo.

---

JobSystem

• Start: JobSystem.Start(workers: 3);

• Schedule: run actions or loops in background threads

• Stop: cancels all tokens and shuts down threads

Example periodic worker:

JobSystem.Schedule(async  ct => {

while (!ct.IsCancellationRequested) {

DmaMemory.ScatterRound(rd => { /* bulk reads */ });

Snapshots.Mutate(s => s  with { Status = "Updated" });

await  Task.Delay(50, ct);

}

});

---

Assets (PNG & SVG)

• PNG:

var  img = Raylib.LoadImage("Assets/Img/Logo.png");

var  tex = Raylib.LoadTextureFromImage(img);

Raylib.UnloadImage(img);

• SVG (via Skia):

Texture2D  tex = SvgLoader.LoadSvg("Assets/Img/Logo.svg", 32);

ImGui.Image((IntPtr)tex.Id, new  Vector2(tex.Width, tex.Height));

Assets are auto-loaded via Assets.Load().

---

Config & style

• Configs are JSON in %AppData%\MamboDMA\<GameName>\config.json

• Use Config<T>.DrawConfigPanel(...) for UI-bound config

• StyleConfig saves ImGui style + fonts

---

Top Info Bar

A slim status bar with:

• Logo (SVG/PNG)

• Project title text

• FPS counter

• Current resolution & refresh rate

• Close button

Position: centered at top of viewport. Auto-resizes width to content.

---

Troubleshooting

• OBS/Discord capture: run with same elevation; disable “fullscreen optimizations”.

• Window icon not updating: ensure .ico contains all sizes (16, 24, 32, 48, 64, 128, 256).

• Fonts missing: check Assets/Fonts copy settings.
