A very early experimental version of DS console emulator for ARM32/PS Vita.
This runs most games, however consider:
- 3D rendering:
- Polygons and their textures are drawn, however no lighting or other shading (e.g. toon) are implemented.
- Games which swap screens every frame for displaying 3D on both screens at the same time, will flicker heavily.
- 2D rendering is mostly complete:
- Mosaic and some window objects (you will see black screens or silhouettes) are not implemented.
- ARM7 HLE will not work with most games:
- Disable it if certain games don't boot further, get struck, crash or have any issues.
- There are other emulation modes like PartialHle or PartialSoundHle. You can pick them if full HLE breaks anything.
- Auto frameskip is always used:
- Games will feel choppy.
Installation
Downoload the latest vpk from releases and install it through VitaShell.
Install libshacccg.suprx, follow this guide.
Install kubridge.skprx from releases.
It's recommend overclocking your Vita to 500MHz, by default they are unchanged.
Create the folder ux0:dsvita and put your roms there.
