{{#seo: |title=Vita Homebrew Emulators (Handheld) - GameBrew |title_mode=append |image=DSVita.png |image_alt=DSVita }} 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, any other shading (e.g. toon) nor shadow volumes 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, you will most likely hover around 15 fps, even if they run at full game speed. *No scanline rendering, thus games that update VRAM mid frame will not render correctly: **Not many games do this, however games that do use it for scrolling texts. == Installation == Downoload the latest vpk from [https://github.com/Grarak/DSVita/releases releases] and install it through [[VitaShell]]. Install libshacccg.suprx, follow this [https://cimmerian.gitbook.io/vita-troubleshooting-guide/shader-compiler/extract-libshacccg.suprx guide]. Install [[Kubridge_Vita|kubridge.skprx]] from [https://github.com/bythos14/kubridge/releases releases]. It's recommend overclocking your Vita to 500MHz, by default they are unchanged. Create the folder ux0:dsvita and put your roms there. ==Screenshots== https://dlhb.gamebrew.org/vitahomebrews/DSVita-01.png https://dlhb.gamebrew.org/vitahomebrews/DSVita-02.png https://dlhb.gamebrew.org/vitahomebrews/DSVita-03.png https://dlhb.gamebrew.org/vitahomebrews/DSVita-04.png ==Media== '''DSVita Ace Attorney''' ([https://www.youtube.com/watch?v=qIdUFbej4dc Willi Ye]) <br> <youtube width="640">qIdUFbej4dc</youtube> ==Changelog== '''v0.6.1''' * Ignore invalid gx cmds (fixes freeze in Final Fantasy XII: Revenant Wings). * Fix wifi rx buffer overflow. * Small 3d speed up. * Fix 3d texture transformations. * Improve HLE compatibility (Mario Kart, Castlevania: Dawn of Sorrow, Super Mario 64, Need for Speed: Underground 2). * Some 3d drawing fixes.

'''v0.5.0''' * Implement fast mem for reading with kubridge. * Implement software fast mem for writing. * Accelerate 3d operations with neon. * Accelerate audio sampling with neon. * Faster JIT compilation. * Implement lookup tables for I/O ports operations. * Faster ROM word lookups. * Remove polygon clipping. * Run scheduler inside guest context. * Use batch I/O operations for DMA and ldm/stm. * Reset jit blocks in chunks. '''v0.4.0''' * Jit rewrite. ** Blocklinking. ** Return stack buffer optimization. * Implement 3d tests. * Improve Arm7 hle compatibility. '''v0.3.1''' *Change ux0:dsvita to ux0:data/dsvita (normal vpks don't have permission to create directories/files at the root).
