Playstation Portable Games with Debug Symbols

Edit on Github | Updated: 04 April 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.

I have never seen a PSP executable that contains the debug symbols inside the elf (eboot) itself, all the games with debug symbols we have come across have been using external .sym and .map files to store the debug information.

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.


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 and Game-dvd.sym.

Games with PRX symbols

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.

  • Flowars (KOR) /PSP_GAME/USRDIR/umodule/flowars.prx
  • SSX On Tour (KOR) (PRX files with lots of debug symbols)

Other Retail Games with Debug Symbols

Outside of games that use the Vicious Engine it is very rare to find games that bundled with their debug symbols, but there are a few games:

  • Need for Speed - ProStreet (Europe) (PSP) (PSN) (big files)
  • Chandragupta Warrior Prince (EUR) - mentions of C-like exports (infernal engine)
