ps2-packer-small

This modded packer doesn't create a packed ELF. Instead, it creates a raw binary file with lzma packed section only. This way, it can be embedded into any ELF (including lzma stub) with arbitrary load adddress.

Based on Nicolas "Pixel" Noble work.

Modules

Compilation will generate ps2-packer-lite, so only lzma module is supported.

Source code and legal stuff

This code is covered by GPL.

How it works

  Usage: ps2-packer [-v]  <in_elf> <out_binary>
  
  Options description:
    -v             verbose mode.
    

Examples

Packing of wLE.

How to compile

Current compilation options requires libz.a and libucl.a to reside at /usr/lib/libz.a and /usr/lib/libucl.a (I do that only to statically link the zlib and ucl with the final software, so it will run everywhere) So, if it doesn't match your system, change that line into the Makefile. Afterward, a simple make should do the trick in order to compile everything, provided you have the full ps2 toolchain, with the PS2SDK variable pointing to your ps2sdk directory, and ee-gcc under your path.

Don't look at the dist target in the Makefile, it's only for me to build the various packages.
