StapleButter b4165cc0a9 3D: keep the rasterizer from accidentally going out of bounds when given very flat X-major edge slopes. 
this, by a fucking shitshow of butterfly effect, ends up fixing #234. technically, the rasterizer was going out of bounds, which, under certain circumstances, caused interpolation to shit itself and generate Z values that were out of range (but still ended up in the zbuffer). sometimes those values ended up negative, which caused these glitches when polygons had to be drawn over those.

about fucking time.

README.md

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
