DS emulator, sorta
|
|
|
|
The goal is to do things right and fast, akin to blargSNES (but hopefully better). But also to, you know, have a fun challenge :)
|
|
<hr>

|

|
## How to use
|
|
|
|
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.
|
|
|
|
### Possible firmware sizes
|
|
|
|
* 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!
|
|
|
|
## How to build
|
|
|
|
### Linux
|
|
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 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 libarchive-dev libzstd-dev`
|
|
* Arch Linux: `sudo pacman -S base-devel cmake extra-cmake-modules git libpcap sdl2 qt5-base qt5-multimedia libarchive zstd`
|
|
3. Download the melonDS repository and prepare:
|
|
```bash
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
|
|
3. Compile:
|
|
```bash
|
|
cmake -B build
|
|
cmake --build build -j$(nproc --all)
|
|
```
|
|
|
|
### Windows
|
|
1. Install [MSYS2](https://www.msys2.org/)
|
|
2. Open the **MSYS2 MinGW 64-bit** terminal
|
|
3. Update the packages using `pacman -Syu` and reopen the terminal if it asks you to
|
|
4. Install git to clone the repository
|
|
```bash
|
|
pacman -S git
|
|
```
|
|
5. Download the melonDS repository and prepare:
|
|
```bash
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
#### Dynamic builds (with DLLs)
|
|
5. Install dependencies: `pacman -S mingw-w64-x86_64-{cmake,SDL2,toolchain,qt5-base,qt5-svg,qt5-multimedia,qt5-tools,libarchive,zstd}`
|
|
6. Compile:
|
|
```bash
|
|
cmake -B build
|
|
cmake --build build
|
|
cd build
|
|
../tools/msys-dist.sh
|
|
```
|
|
If everything went well, melonDS and the libraries it needs should now be in the `dist` folder.
|
|
|
|
#### Static builds (without DLLs, standalone executable)
|
|
5. Install dependencies: `pacman -S mingw-w64-x86_64-{cmake,SDL2,toolchain,qt5-static,libarchive,zstd}`
|
|
6. Compile:
|
|
```bash
|
|
cmake -B build -DBUILD_STATIC=ON -DCMAKE_PREFIX_PATH=/mingw64/qt5-static
|
|
cmake --build build
|
|
```
|
|
If everything went well, melonDS should now be in the `build` folder.
|
|
|
|
### macOS
|
|
1. Install the [Homebrew Package Manager](https://brew.sh)
|
|
2. Install dependencies: `brew install git pkg-config cmake sdl2 qt@6 libarchive zstd`
|
|
3. Download the melonDS repository and prepare:
|
|
```zsh
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
4. Compile:
|
|
```zsh
|
|
cmake -B build -DCMAKE_PREFIX_PATH="$(brew --prefix qt@6);$(brew --prefix libarchive)" -DUSE_QT6=ON
|
|
cmake --build build -j$(sysctl -n hw.logicalcpu)
|
|
```
|
|
If everything went well, melonDS.app should now be in the `build` directory.
|
|
|
|
#### Self-contained app bundle
|
|
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.
|
|
|
|
## TODO LIST
|
|
|
|
* 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)
|
|
|
|
### TODO LIST FOR LATER (low priority)
|
|
|
|
* 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
|
|
|
|
## Credits
|

|
|
* Martin for GBAtek, a good piece of documentation
|
