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 :)
The source code is provided under the GPLv3 license.
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:
mkdir -p build
cd build
cmake ..
make
Windows:
- use CodeBlocks
- or receive golden cookies if you get Cmake to work
Build system is not set in stone.
TODO LIST
- improve libui and the emulator UI
- fix occasional sound crackling in games that use surround (timing issue?)
- 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
- hardware renderer for 3D (w/ upscaling and fancy shit)
- 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
