PSPLibDoc

An attempt to document symbols of PSP modules across all firmwares.
Page with the current NID status for each library can be found here.

Usage

Prerequisites

psp_libdoc.py and psp_print_libdoc.py require python3 with lxml module.

Common psp_libdoc operations

• Loading source files

  • Load one or more PSPLibDoc XML files

    • psp_libdoc.py -l input_1.xml input_2.xml input_3.xml...

  • Load one or more PSP export files

    • psp_libdoc.py -e input_1.exp input_2.exp input_3.exp...

  • Load one or more PPSSPP source files (HLEFunction arrays)

    • psp_libdoc.py -p input_1.cpp input_2.cpp input_3.cpp...

  • Combination of multiple different sources

    • psp_libdoc.py -l input_1.xml input_2.xml... -e input_1.exp input_2.exp... -p ...

• Save a combined PSPLibDoc XML file from all loaded sources

  • psp_libdoc.py sources -c psp_libdoc.xml
  • save_combined.sh will create a combined PSPLibDoc file for all firmwares

• Save PRX modules as individual PSPLibDoc XML files from all loaded sources

  • psp_libdoc.py sources -s outputFolder

• Update a PSPLibDoc XML file with known NIDs from all loaded sources

  • psp_libdoc.py sources -u psp_libdoc_to_update.xml
  • update_imports.sh will update the Import files for all firmwares from the combined PSPLibDoc

• Update the PSPLibDoc XML files of all firmwares from PSP export files (*.exp)

  • Put all export files into an input folder and name them after the prx it should update
  • Example: ata.exp, sysmem.exp in inputFolder will update ata.xml and sysmem.xml across all firmwares
  • ./update_from_psp_exports.sh inputFolder

• Export all unknown NIDs from all loaded sources

  • psp_libdoc.py sources -o unknown_nids.txt

• Export all known function names from all loaded sources

  • psp_libdoc.py sources -k known_function_names.txt

Common psp_print_libdoc operations

• Print all exports of a given PRX module

  • psp_print_libdoc.py -d directory -e module
  • Example: psp_print_libdoc.py -d PSPLibDoc/1.50/ -e sysmem

• Print all imports of a given PRX module

  • psp_print_libdoc.py -d directory -i module
  • Example: psp_print_libdoc.py -d PSPLibDoc/1.50/ -i threadman

• Print all PRX modules exporting a given library

  • psp_print_libdoc.py -d directory -l library
  • Example: psp_print_libdoc.py -d PSPLibDoc/1.50/ -l SysMemForKernel

• Print all PRX modules importing a given library

  • psp_print_libdoc.py -d directory -m library
  • Example: psp_print_libdoc.py -d PSPLibDoc/1.50/ -m LoadCoreForKernel

General Notes

• psp_libdoc currently does not load or save variables (Updating a PSPLibDoc however preserves variables)
• Updating a PSPLibDoc is based on NID only, a loaded entry with the same NID will overwrite the previous one

Firmware Notes

• Firmware 1.00 is an accidentally leaked pre-release firmware by Sony (also known as 1.00 Bogus)
• Firmware 1.03 is the actual PSP Japan release firmware (VSH only reports 1.00)
• Firmwares in the ePSPVitaLibDoc folder refer to PS Vita firmware
• The PS Vita ePSP emulator was based on different PSP firmwares throughout its lifecycle
  • Since PS Vita ePSP 0.931 -> PSP 6.20
  • Since PS Vita ePSP 0.990 -> PSP 6.36
  • Since PS Vita ePSP 1.03 -> PSP 6.60
  • Since PS Vita ePSP 3.36 -> PSP 6.61
