{{#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 ** Mostly implemented *** Z fighting can occur *** Games using 3D on both screen will have bad framerates *** Some effects like fog are unimplemented * 2D rendering is mostly complete * 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 SoundHle. You can pick them if full HLE breaks anything * Auto frameskip is always used ** Games will feel choppy, you will most likely hover around 20-30 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 == Download 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] or just install and open [[VitaDB_Downloader|VitaDB]]. 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== '''v0.9.2''' * Fix screen layout settings not being persistent * Fix some 3d translucent rendering bugs * Minor gx fifo parsing speedup * Minor CPU emulation speedup * Add widescreen options * Add more upscaling options * Improve 3d rendering framerate * Implement Retroachievements (very experimental) '''v0.9.1''' * Allow palette I/O operations outside of mapped memory (fixes Newer Super Mario Bros.
