The goal is to do things right and fast, akin to blargSNES (but hopefully better). But also to, you know, have a fun challenge :)

Firmware boot (not direct boot) requires a BIOS/firmware dump from an original DS or DS Lite.DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly.

• 128KB: DSi/3DS DS-mode firmware (reduced size due to lacking bootcode)
• 256KB: regular DS firmware
• 512KB: iQue DS firmware

DS BIOS dumps from a DSi or 3DS can be used with no compatibility issues. DSi BIOS dumps (in DSi mode) are not compatible. Or maybe they are. I don't know.

As for the rest, the interface should be pretty straightforward. If you have a question, don't hesitate to ask, though!

1. Install dependencies:

   • Ubuntu 22.04:sudo apt install cmake extra-cmake-modules libcurl4-gnutls-dev libpcap0.8-dev libsdl2-dev qtbase5-dev qtbase5-private-dev qtmultimedia5-dev libslirp-dev libarchive-dev libzstd-dev
   • Older Ubuntu:sudo apt install cmake extra-cmake-modules libcurl4-gnutls-dev libpcap0.8-dev libsdl2-dev qt5-default qtbase5-private-dev qtmultimedia5-dev libslirp-dev libarchive-dev libzstd-dev
   • Arch Linux:sudo pacman -S base-devel cmake extra-cmake-modules git libpcap sdl2 qt5-base qt5-multimedia libslirp libarchive zstd

2. Download the melonDS repository and prepare:

   git clone https://github.com/melonDS-emu/melonDScd melonDS

3. Compile:

   cmake -B buildcmake --build build -j$(nproc --all)

1. InstallMSYS2
2. Open theMSYS2 MinGW 64-bit terminal
3. Update the packages usingpacman -Syu and reopen the terminal if it asks you to
4. Install git to clone the repository

   pacman -S git

5. Download the melonDS repository and prepare:

   git clone https://github.com/melonDS-emu/melonDScd melonDS

5. Install dependencies:pacman -S mingw-w64-x86_64-{cmake,SDL2,toolchain,qt5-base,qt5-svg,qt5-multimedia,qt5-tools,libslirp,libarchive,zstd}
6. Compile:

   cmake -B buildcmake --build buildcd build../tools/msys-dist.sh

If everything went well, melonDS and the libraries it needs should now be in thedist folder.

5. Install dependencies:pacman -S mingw-w64-x86_64-{cmake,SDL2,toolchain,qt5-static,libslirp,libarchive,zstd}
6. Compile:

   cmake -B build -DBUILD_STATIC=ON -DCMAKE_PREFIX_PATH=/mingw64/qt5-staticcmake --build build

If everything went well, melonDS should now be in thebuild folder.

1. Install theHomebrew Package Manager
2. Install dependencies:brew install git pkg-config cmake sdl2 qt@6 libslirp libarchive zstd
3. Download the melonDS repository and prepare:

   git clone https://github.com/melonDS-emu/melonDScd melonDS

4. Compile:

   cmake -B build -DCMAKE_PREFIX_PATH="$(brew --prefix qt@6);$(brew --prefix libarchive)" -DUSE_QT6=ONcmake --build build -j$(sysctl -n hw.logicalcpu)

If everything went well, melonDS.app should now be in thebuild directory.

If you want an app bundle that can be distributed to other computers without needing to install dependencies through Homebrew, you can additionally run ../tools/mac-bundle.rb melonDS.app after the build is completed, or add-DMACOS_BUNDLE_LIBS=ON to the first CMake command.

• better DSi emulation
• better OpenGL rendering
• netplay
• the impossible quest of pixel-perfect 3D graphics
• support for rendering screens to separate windows
• emulating some fancy addons
• other non-core shit (debugger, graphics viewers, etc)

• big-endian compatibility (Wii, etc)
• LCD refresh time (used by some games for blending effects)
• any feature you can eventually ask for that isn't outright stupid

• Martin for GBAtek, a good piece of documentation
• Cydrak for the extra 3D GPU research
• limittox for the icon
• All of you comrades who have been testing melonDS, reporting issues, suggesting shit, etc
