Well it is already planned to reduce the file size limit used for md5 
checksums to 128KB for the SCUMM engine.

If the file size details are required to reduce file access, we might as 
well just update the md5 checksums with an even smaller file size limit. 
Since the md5 details have to be updated in either case.
