Playstation Portable Games with Debug Symbols

Edit on Github | Updated: 07 July 2020

The Sony Playstation portable used encrypted executables known as EBOOT.BIN, these are basically just an encrypted ELF file and it is possible to decrypt them with the correct tools. Some games also ship with unencrypted executables in BOOT.BIN


Types of PSP Symbol files

SYM Symbol Files

.SYM Files are generated by the SN Systems ProDG SDK for PSP for use in debugging, they contain all the symbols (function names etc) and can also contain other chunks such as source filenames and line numbers.

MAP Symbol Files

Similar to .sym files but are created by the linker to document where each function is located in the final linked executable.


BOOT.BINs with Debug Symbols

  • Adventure Player (Japan) (v1.05)
  • Armored Core - Formula Front (Korea) (v1.02)
  • Astonishia Story (Korea) (v1.02)

  • Space Invaders - Galaxy Beat (Japan) (v1.02)
  • Yu-Gi-Oh! Duel Monsters GX - Tag Force (Japan) (En,Ja,Fr,De,Es,It) (v1.02)

ViciousEngine

Many games using the ViciousEngine actually came with both the .sym and .map files compressed inside the DATA.PAK file. ViciousEngine was one of the few game engines recommended officially by Sony, and in fact they offered a discount for the engine if it was used to create a PSP Mini [^1].

You can extract the .sym and .map file by opening the PSP_GAME/USRDIR/DATA.PAK with

The DATA.PAK file normally contains some files with a name that is a variation of Game-dvd.map and Game-dvd.sym.

Some games implement some major parts of the game logic in prx files rather than in the EBOOT executables. The PRX format contains lots of debug information as its basically a library.
