tiny C tool to patch the large address aware flag on windows executables.

lets 32-bit applications (.exe or .dll) use more than 2GB of RAM when running in a 64-bit envrionment (e.g. old games like final fantasy xi),

pure C, lightweight, no dependencies.

pre-compiled binaries for linux and windows are here, with instructions in the zip:

releases page

install gcc and make

clone the repo and run make linux

git clone https://github.com/kkslidermight/laa.git
cd laa
make linux

the binary will be at build/linux/laa. copy to the path-accessible directory of your choice or just run it from there.

install gcc from MinGW-w64 or have cl.exe from visual studio build tools in your PATH.

clone the repo and run make windows

git clone https://github.com/kkslidermight/laa.git
cd laa
make windows

the binary will be at build/windows/laa.exe.

run ./laa (linux) or .\laa.exe (windows) from the terminal and point it to your desire executable.
be sure to back up the original exe first.

example:

# linux
./laa mygame.exe

# windows (powershell or cmd)
.\laa.exe mygame.exe
