Way back in the Dark Ages I used to hack on FAT-12 code...
Going *way* back in the archives - (had to find a 5-1/4 inch floppy
drive!) it looks as if there are directory entry attributes at the byte
at dirptr+11, and the lower bits (ANDed with 0x1C) should be 0. Otherwise,
if I recall (don't have reference books here), there is a bit saying
the file is deleted (other bits say subdirectory, system file, etc.)
So you may just have to change that one byte (per file) to recover them
(in addition to changing the first byte of the file name which you
already did).
Hope this helps...
(otherwise find a copy of Norton Disk Doctor... :)
