Sorry, I see that it is possible to extract the data with the current version.
Please use:
var RB: RawByteString;
IEGlobalSettings.EXIFMakerNotesHandling := iemhDecodeOrMaintainRaw;
ImageEnView1.io.LoadFromFile(FileListBox1.FileName);
SetLength(RB, ImageEnView1.IO.Params.EXIF_MakerNote.UnparsedDataLength);
Move(ImageEnView1.IO.Params.EXIF_MakerNote.UnparsedData^, Pointer(RB)^, ImageEnView1.IO.Params.EXIF_MakerNote.UnparsedDataLength);
memo1.Text := RB;
