melonDS
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 :)
## How to use
melonDS requires BIOS/firmware copies from a DS. Files required:
* bios7.bin, 16KB: ARM7 BIOS
* bios9.bin, 4KB: ARM9 BIOS
* firmware.bin, 128/256/512KB: firmware
Firmware boot requires a 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:
* Install dependencies:
```sh
sudo apt-get install cmake libcurl4-gnutls-dev libpcap0.8-dev libsdl2-dev qtbase5-dev qtdeclarative5-dev libslirp-dev libarchive-dev
```
* Compile:
```sh
mkdir -p build
cd build
cmake ..
make -j$(nproc --all)
```
### Windows:
1. Install [MSYS2](https://www.msys2.org/)
2. Open the **MSYS2 MinGW 64-bit** terminal
3. Update the packages using `pacman -Syu` and reopen the terminal if it asks you to
#### Dynamic builds (with DLLs)
4. Install dependencies: `pacman -S git make mingw-w64-x86_64-{cmake,mesa,SDL2,toolchain,qt5,libslirp,libarchive}`
5. Run the following commands
```bash
git clone https://github.com/Arisotura/melonDS.git
cd melonDS
mkdir build
cd build
cmake .. -G "MSYS Makefiles"
make -j$(nproc --all)
../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)
4. Install dependencies: `pacman -S git make mingw-w64-x86_64-{cmake,mesa,SDL2,toolchain,qt5-static,libslirp,libarchive}`
5. Run the following commands
```bash
git clone https://github.com/Arisotura/melonDS.git
cd melonDS
mkdir build
cd build
cmake .. -G 'MSYS Makefiles' -DBUILD_STATIC=ON -DQT5_STATIC_DIR=/mingw64/qt5-static
make -j$(nproc --all)
mkdir dist && cp melonDS.exe dist
```
If everything went well, melonDS should now be in the `dist` folder.
### macOS:
1. Install the [Homebrew Package Manager](https://brew.sh)
2. Install dependencies: `brew install git pkg-config cmake sdl2 qt@5 libslirp libarchive`
3. Compile:
```zsh
git clone https://github.com/Arisotura/melonDS.git
cd melonDS
mkdir build && cd build
cmake .. -DQt5_DIR=$(brew --prefix qt5)/lib/cmake/Qt5
make -j$(sysctl -n hw.ncpu)
mkdir dist && cp -r melonDS.app dist
```
If everything went well, melonDS.app should now be in the `dist` folder.
## TODO LIST
* DSi emulation
* the impossible quest of pixel-perfect 3D graphics
* improve libui and the emulator UI
* support for rendering screens to separate windows
* emulating some fancy addons
* other non-core shit (debugger, graphics viewers, cheat crapo, etc)
### TODO LIST FOR LATER
* better wifi
* maybe emulate flashcarts or other fancy hardware
* 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
