Build your relinker command.

& '.\relinker.exe' --windows 'source/input.elf' 'app.exe'

Before running the command

1. Check the relinker filename. The command assumes relinker.exe on Windows or relinker on Linux, in the current directory. Adjust it to your downloaded filename.
2. Check the output format. The Windows selection adds --windows. A filename extension alone does not select PE output.
3. Prepare the runtime separately. Conversion does not provide your application's resources or replace the need for target-specific AnyPS5 system libraries.
4. Read the output. A conversion success says nothing about a title's playable state. Keep the printed module paths and first error for diagnosis.

For --rpath, unused-import analysis, or deprecated debugging switches, consult the original usage document. The default library path is $ORIGIN/libs; quote $ORIGIN when setting a custom path in a shell.
