How to check version of SDK in use

You are really just looking for a string of the form “PSII* 2720” where the * denotes text that can change based on which library you search.

You can search for Games that match a specific SDK version by running the following bash command:

find . -name "MCMAN.IRX" -print0 | xargs -0 strings | grep -Hn "   272"

Replace 2720 with the version number you want, e.g 272 is 2.7.2

Running PS2 Official SDK under 64-bit ubuntu Linux

By default the 64-bit version of ubuntu does come with the 32bit libraries that the SDK binaries have been linked to. So when you try to run any of the binaries it gives an error such as:

iop-gcc: command not found

In order to fix this you need to run the following commands:

sudo apt-get update; sudo apt-get upgrade; sudo apt-get install ia32-libs
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install lib32z1

SDK Contents

Emotion Engine (EE) Toolchain

The Emotion Engine Toolchain was developed by Cygnus based on GNUPro and has support for running the toolchain on windows, linux and Solaris.

Tool Description
ee-gcc C compiler modified from GNU GCC
ee-g++ C++ GNU compiler
ee-as GNU Assembler
dvp-elf-as GNU Assembler for DVP (Vector unit Assembler?)
ee-ld GNU Linker (Link object files together to create libraries)
ee-gbd Standard GNU Debugger
ee-run Simulator
sky.ld Script that calls the Linker?
ee-addr2line Get filenames and lines numbers from program addresses
ee-ar GNU Archive handler
ee-c++filt Demangle C++ symbols
ee-nm print the list of symbols contained in an object file
ee-objcopy Copy object files
ee-objdump Standard GNU object dumper to display information about an object
ee-ranlib List the index of an archive
ee-size Display the size of sections in a file
ee-strings Standard SNU strings utility to get strings from binary files
ee-strip Strip an executable to remove debugging symbols


One important point is that generating debug symbols doesn’t ever modify the code generation but there are some optimisation flags that can make debugging more difficult.

Emotion Engine Simulator

The simulator was released before developers got access to the hardware 3, it is basically an emulator which virtualizes the hardware of the emotion engine on a standard pc. This emulator was not cycle-accurate so was not guaranteed to produce the same result as running on the physical hardware.
