Install this emulator's files

With Batocera, RetroBat, EmuDeck, RetroDECK, ROCKNIX or KNULLI: the installer finds Batocera, RetroBat, EmuDeck, RetroDECK, ROCKNIX or KNULLI and its BIOS folder, then downloads only the files Vita3K reads there and checks each one.

Technical notes

Standalone PS Vita emulator. No libretro core. Firmware installed via File > Install Firmware or CLI --firmware flag. PUP files validated by SCEUF magic header only (vita3k/packages/src/pup.cpp:119), no hash check. After install, four partitions are extracted: os0 (FAT, kernel modules), vs0 (FAT, system modules/apps), sa0 (FAT, fonts), pd0 (exFAT, system data/BGM). Module loading: app0:sce_module/{name}.suprx (game-bundled) then vs0:sys/external/{name}.suprx (firmware). Auto-LLE modules include libhttp, libssl, libult, libsas, libpgf, libfios2, libsystemgesture, libSceXml, libSceSqlite, librudp, libatrac, libface, libsmart, libsceavplayer, libSceJson, and more (vita3k/module/src/load_module.cpp:142-162). A third optional preinst firmware PUP (pd0 partition: system BGM, resources) is available from Sony but not commonly required for game compatibility.

Files

2 files: 1 required, 1 optional. 2 have an HLE fallback.

In this collection: 2 in repo and 0 missing.

Required

PSVUPDAT.PUP required in repo HLE fallback

• Path: psvita/PSVUPDAT.PUP
• Main PS Vita firmware. Decrypted via SCE keys, extracts os0 (kernel), vs0 (system modules and apps), sa0 (fonts), pd0 (system data). Games load LLE modules from vs0/sys/external/*.suprx. Preload modules (libc, libSceFt2, libpvf) are always LLE. Without firmware most games fail. Some simple titles may run on HLE alone.

• Collection copy: bios/Sony/PlayStation Vita/PSVUPDAT.PUP
• Platforms: psvita/PSVUPDAT.PUP: Batocera, KNULLI

Source

• Source: vita3k/packages/src/pup.cpp:260-314, vita3k/app/src/app.cpp:176, vita3k/module/src/load_module.cpp:142-161, vita3k/module/src/load_module.cpp:187

Optional

PSP2UPDAT.PUP optional in repo HLE fallback

• Path: psvita/PSP2UPDAT.PUP
• Supplementary firmware font package. Populates the sa0 partition with system fonts (PVF format), which the renderer registers as the firmware font directory when the partition holds content.

• Collection copy: bios/Sony/PlayStation Vita/PSP2UPDAT.PUP
• Platforms: psvita/PSP2UPDAT.PUP: Batocera, KNULLI
