mc_import.exe copies ICO's save (of any of the discs) out
of a PS2 memory card file or save archive into the game's save folder.
Playing the game does not need it.
To run it, open a Command Prompt in this folder and give it the file.
Add --to with the folder to copy into, then the file's name, for example:
  mc_import.exe --to "%APPDATA%\ico-pc\ico-pc\memcard" Mcd001.ps2
The steps are in docs\PORTABLE_MODE.md, "Bring a PS2 save over".
SDL3.dll is a library mc_import.exe needs beside it.
