Yet Another 4Gb Patch

Tiny CLI utility that sets the LARGEADDRESSAWARE flag on 32-bit Windows executables, allowing them to use up to 4GB of RAM on 64-bit systems.

Usage

Warning

It modifies the PE header in-place. Backup your file if you're paranoid.

ya4gb_patch.exe target_program.exe

Notes

• Works only on 32-bit .exe files.
• On 64-bit Windows, this lifts the default 2GB RAM cap to 4GB.
• On 32-bit systems, it does nothing useful.
