[V0.3] love-pe - A 100% lua library for manipulating windows PE files (exe/dll)
Posted: Fri May 11, 2018 8:07 am
Hello everyone 
,
I've been working on a library for manipulating PE files (.exe/.dll) using only Lua and LÖVE, it mainly focuses on hacking the resources.
The main goal of creating this library is to make it possible to change love.exe icon using LÖVE itself, The library is currently not complete and it's like 10% only of my plans.
IconPatcher Usage:
This version (v0.3) replaces the icon by patching the executable, instead of rebuilding it, so it has much more stability, it could only break the checksum which is 0 for more executables.
The resulting executable will have the exact size of the old one.
The new icon should contain the same image sizes of the exe one, otherwise the non-matching images won't be updated.
And because .ico uses bmp format, then as long as the .ico has the same images sizes and bpp then they will have the same file size.
When reporting a non working '.exe', please upload the '.exe' and '.ico' and create a github issue: https://github.com/RamiLego4Game/love-pe/issues
lovePE API:
Copy the love-pe.lua file from this repo into your own project, and here's the API documentation (It's available at the top of the script):

- Install LÖVE 11.1.
- Download IconPatcher-V0.3.love (From github releases, link at the end of the post).
- Download LÖVE for Windows (32-bit or 64-bit, both supported), from https://love2d.org.
- Create a new icon using your favorite image editor.
- Run the downloaded .love using LÖVE.
