ndsemu

Status

This emulator is still in DEVELOPMENT PHASE.

Some games work and are playable, others have broken graphics, others crash almost immediately.

ARM
- Most opcodes implemented in both ARM and Thumb mode
- Disassemly for debugging support
- Correct cycle counting
- Correct handling of miasligned memory addresses
- Preliminar JIT (not fully working yet)
2D: BG layers
- Text mode (16/256 colors, scrolling)
- Affine modes (16bit bgmap, 8bit bitmap, direct bitmap)
- Different map sizes
- Priorities
- Extended palettes
2D: OBJ (sprites)
- Normal sprites
- Different sizes
- Extended palettes
- Bitmaps
- Affine (rotozoom)
2D: advanced modes
- VRAM display mode
2D: misc features
- Capturing: only basic support (normal BG+OBJ capture)
- Master brightness
- Window (OBJ and BG)
- Color special effects
3D: geometry processor
- Most commands implemented
- Accurate timing
3D: rasterizer
- Quadrangle splitting
- Backface culling
- Triangle rasterization
- All different texture formats
- Texture perspective correction
- Clipping
- Lighting and materials (with bugs...)
- Toon shading
Sound
- PCM channels
- Noise

To compile, you must clone into a ndsemu subdirectory:

git clone https://github.com/rasky/ndsemu $GOPATH/src/ndsemu
cd $GOPATH/src/ndsemu
go get
go build

You need access to an official NDS BIOS and firmware. Put them within a "bios" subdirectory, like this:

ndsemu
  |---bios
       |---- firmware.bin
       |---- biosnds7.rom
       |---- biodnds9.rom

At this point, you can just run it with:

./ndsemu <path-to-your-rom-file>
