Large Address Aware PowerShell Tools

Enable 4GB RAM usage for 32-bit Windows applications using pure PowerShell scripts - no external tools or Visual Studio required.

What This Does

Modifies the PE header of 32-bit executables to set the LARGE_ADDRESS_AWARE flag, allowing them to use up to 4GB of RAM on 64-bit Windows systems (instead of the default 2GB limit).

Why Use This?

• No external downloads - Uses built-in Windows PowerShell
• No Visual Studio required - Alternative to editbin.exe
• Safe - Creates automatic backups before modification
• Open source - See exactly what it does to your files
• Lightweight - Just a few KB of PowerShell code

Perfect For

• 32-bit games that run out of memory (Mafia II, older titles)
• Legacy business applications
• Development tools with memory constraints
• Anyone who needs PE header modification without installing Visual Studio
