Description

It would be great to be able to extract files from an ISO image in RAW mode, i.e. to return 2352 bytes per sector without any attempt to further process its content such as returning only the user data part, attempting error correction and so on.

Maybe an extra parameter to extract a single file like the following pseudo command could do:

program.exe -input_file "abcd.cue" -extract-file "\movie.str" -mode raw

This would simply read the file sectors in RAW and write the file accordingly.

A use case would be to extract PSX video files properly.

Currently this is how I do it:

extract the movie file in RAW mode with isobuster
convert it to AVI using jpsxdec

If the file is not extracted in RAW mode, the former wouldn't detect any stream in the file, i.e. there is vital information in the non user data parts of a sector.
