BTW, if you are going to try Hachman, don't get the latest 8.x release on the
homepage. It introduces a low file size limit in the freeware version, making it unusable for editing the data.000 file. It is still possible to find the previous 7.x release, though; check
here, or search
Google for "hack704.zip" or "hack702.zip", etc.
Alternately, there are other the freeware programs, such as
Frhed,
XVI32 or those listed
here or reviewed on
this site.
