DualiS Frequently Asked Questions

"I'm trying to run a binary and the emulator crashes"
This version of Dualis only supports ARM9 binaries. The emulator loads the binary into main memory starting at 0x2004000, and then executes it from there.
Make sure you're not trying to run a binary containing code for the ARM7, or one that relies on being executed from ROM.
If it still doesn't work, then your code is probably relying on some feature which hasn't yet been implemented in Dualis.

"Performance is really slow"
Emulating a machine like the DS is a demanding task. With a processor running at 2 GHz or more, and a decent graphics card you should be able to reach acceptable speeds. If your graphics card has poor support for reversed 15-bit texture format you might get a performance bottleneck in the GPU.

"3D demos give no output when the D3D renderer is selected"
The D3D renderer is unfinished and does not handle 3D hardware command mappings yet.

"My textures are missing"
That's because texture mapping isn't emulated in this version.

"The perspective is wrong in 3D mode"
This is a known bug, which stems from the way 3d hardware commands are emulated in this version.

ARM7TDMI Nothing.

Video Both screens are emulated.
The following modes are emulated (more or less):

BG_MODE0
BG_MODE1
BG_MODE2
BG_MODE3
BG_MODE4
BG_MODE5
BG_MODE6 (main core)
MODE_FB0..FB3 (main core)

All color effects are emulated (except for alpha-
blending on BGs using extended palettes).
The 3D-hardware commands are mapped directly
onto OpenGL. There are some problems with the
matrix stacks in this release, which causes
perspective errors in most 3D demos.

Audio Nothing.

Input All keys except X and Y are emulated.
Touchscreen input is faked using the IPC method
implemented in NDSLib.

DMA DM1, DM2 and DM3 are emulated.

Timers All timers are emulated in both prescalar and count-up mode.

Interrupts Vblank, hblank, key, DMA and timer interrupts are emulated,
though not completely accurate.
