PKTINY, also written PK-TINY, is an executable compression utility that tries to make life difficult for those who want to decompress such files. It was developed by VGA-Software and Thomas Mönkemeier.
It compresses DOS EXE files (to EXE), and COM files (converting them to EXE). The files it creates are a corruption of TINYPROG format, but superficially look more like PKLITE.
Only version 1.62 has been found, but there were others. UnTiny v1.04 says it supports "PKTiny 1.0, 1.4, 1.5, 1.60 (from VGACOPY.EXE), 1.61, 1.62".
[edit] Identification
A PKTINY-compressed file normally has the ASCII string "Program was modified and will not run." somewhere in it. Many files, but not all, also contain the string "This program runs only on i80286 and above.".
Like most PKLITE-compressed files, pristine PKTINY files have "PKLITE Copr." at offset 30.
All known PKTINY files have bytes 02 00 at offset 8, and 00 01 00 00 at offset 20 (refer to MS-DOS EXE#Header structure for an explanation of these fields).
[edit] Software
- PKTINY v1.62
- ANORMAL's DOSEXE collections → Executable Tools Pack → packers/pktiny.162-vga soft.rar
Dependencies:
Decompression:
- UnTiny v1.04
- Some other TINYPROG decompressors support PKTINY; see TINYPROG#Software.
