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:

sudo apt-get install libpcap0.8-dev libcurl4-gnutls-dev libsdl2-dev gtk+-3.0

Compile:

mkdir -p build
cd build
cmake ..
make

Windows:

use CodeBlocks

MSYS2 and CMake

Install MSYS2
Open the MSYS2 MinGW 64-bit terminal
Update the packages using pacman -Syu and reopen the terminal if it asks you to
Install dependencies: pacman -S mingw-w64-x86_64-{toolchain,SDL2,cmake} make git

Run the following commands

git clone https://github.com/Arisotura/melonDS.git
cd melonDS
mkdir build
cd build
cmake .. -G "MSYS Makefiles"
make -j5
../msys-dist.sh

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

TODO LIST

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
