No BIOS or firmware files required. This core is self-contained.

Vita3K requires the official PS Vita firmware (PSVUPDAT.PUP) from Sony for full compatibility. The firmware is decrypted using SCE keys and extracted into four partition images: os0 (kernel), vs0 (system), sa0 (assets), pd0 (data).

The most important firmware components are: 1. vs0/sys/external/.suprx - Firmware modules loaded by games 2. sa0/data/font/pvf/.pvf - System fonts (ltn0.pvf is checked at startup) 3. vs0/data/internal/ - LiveArea resources and default themes

Vita3K uses a hybrid LLE/HLE approach: - Some modules (libc, libSceFt2, libpvf, libcdlg) are always loaded from firmware (LLE) - Others can be toggled between LLE and HLE per module via settings - Without firmware, many games will fail to load required modules

The module loading path is: first check app0:sce_module/{name}.suprx (game-bundled), then fall back to vs0:sys/external/{name}.suprx (firmware). This allows games to ship their own module versions.

CLI firmware install: vita3k --firmware /path/to/PSVUPDAT.PUP GUI: File > Install Firmware

Vita3K does not have a libretro core. It is standalone only.
