# 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:
```sh
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
## Credits
* Martin for GBAtek, a good piece of documentation
* Cydrak for the extra 3D GPU research
* All of you comrades who have been testing melonDS, reporting issues, suggesting shit, etc
