Version:

  1.0.0

    - Initial Release

  

Installation:

   1. Copy Playtime.dll into your OllyDbg Plugin directory.

   2. Copy the Lua directory to the same location where OllyDbg.exe is.

   3. Enjoy

   

Using Lua:

   There are 2 variants to execute lua scripts:

     1. Anything in Lua\autorun will be executed as soon the process is ready, we did this 

        to give the scripts a chance to detour functions before starting to debug, you are

        not restricted at this point.

     2. Executing a script over the menu is probably your right choice to create individual

        scripts and execute them on-demand.

     NOTE: There is also one file which is autoloaded internally, it resides in Lua\core\core.lua

           It is not recommended to modify the core files.

   

   We also managed to automate the documentation of all available functions from OllyDbg

   in Documentation.html, please refer to this file to learn more about functions and

   constants.

   One big advantage of this Plugin is the usage of LuaJIT. If you are not aware of what LuaJIT is

   or what its capable of then you missed something big, LuaJIT allows to use C declarations inside

   your Lua script to use native C code, you can get more information about LuaJIT's FFI library 

   on the authors website: 

   http://luajit.org/ext_ffi.html 

   Please keep in mind that our documentation generator is not reading the Lua files at the moment,

   please check some examples shipped within this package to get some insight of whats possible with

   Lua.

NX Breakpoints:

   We also took the opportunity to implement NX Breakpoints into OllyDbg which allows you to break

   as soon a specific memory region is being executed. The difference between a memory breakpoint and

   NX breakpoint is that it will not break if the memory is read and only if executed which makes

   a huge difference in debugging. To make use of NX breakpoints please enable DEP and you have to

   eventually enable the XD/NX flag in your BIOS.

   

   If you are still on Windows XP you must enable the PAE in order to enable NX breakpoints.

Dumper:

   Playtime also has its own PE Image dumper, at the moment its preliminary and will receive further

   features and updates over the time. For now its capable of simple dumping and fixing headers from

   the disk. Later versions will include import rebuilding and more advanced options.
