The following items are new, changed, or fixed from version 1.13
of PKLITE in this release of version 1.14 of the PKLITE software.
Shareware version:
- On rare occasions with certain executables the PKLITE 1.13
extractor may set the stack to collide with the extractor code.
This has been fixed with version 1.14.
- The following file names will not be compressed and must be
renamed if you wish to compress them:
COMMAND.COM
SETVER.EXE
- PKLITE will now compress EXE files with up to approximately
32,000 relocations. Earlier versions were limited to about
15,000 relocations.
- Occasionally an incorrect 'Read-Only, skipping file' message
would occur when the file is not read only. This has been
fixed.
- The output path specified when compressing files to another directory
may now have a trailing slash or backslash.
- Added code to prevent a file being compressed from overwriting itself
when specifying an output path.
Professional version:
- Same changes as above.
- A minor anamoly in the relocation code for files compressed with
the extra compression option has been corrected.
- Changes have been made to make this version more resistant to
"disliting".
- The extra compression option now writes the characters 'PK'
(50, 4B hex) into the psp at offset 5C hex. The user program
can check for this signature and abort if it isn't found. This
way the user program will not run if the PKLITE compression is
removed. This check may look something like the following in
Microsoft or Borland C:
if (*(unsigned int far *)MK_FP(_psp, 0x5C) != 0x4B50)
exit(1);
