This means the ROM file you downloaded is missing specific data chips or contains an older version of the game code that doesn't match the database of version 1.62. Ensure your ROM set is explicitly verified to work with Winkawaks 1.62 or MAME-compatible sets from the same era.
When searching for and downloading ROM sets online, always ensure you scan downloaded archives with up-to-date antivirus software. Be cautious of websites requiring you to download custom download managers or .exe files to access game ROMs, as legitimate ROMs will always come in .zip , .rar , or .7z formats.
