Usage

Generating Card Bitmaps/RES File

Using card_generator.py

$ python card_generator.py -h
Usage: card_generator.py
Edit script to select text, characters, and suits

Building the RES File

Note: Requires windres or rc.exe

windres cards.rc  -o cards.res

or

rc.exe /fo cards.res cards.rc

Building the Weaponized DLL

Note: This is just one method; Visual Studio or another C++ compiler/IDE can be used

1. Download MSYS2
2. Run MSYS2 and download GCC and 32/64-bit toolchains:

pacman -S mingw-w64-x86_64-gcc
pacman -S --needed base-devel mingw-w64-x86_64-toolchain
pacman -S --needed base-devel mingw-w64-i686-toolchain

3. Compile the weaponized DLL:

g++ -Werror -static -mdll -o cards_weaponized.dll cards_proxy.cpp cards.def

Remember: Use your knowledge and skills for good and fun, not evil (not even evil fun)
