[ About this Program ]

DOSKrunch — Packs files into self-extracting DOS .EXE archives, tuned per CPU.

DOSKrunch takes a pile of files on a modern machine (Linux, macOS, or Windows) and emits one self-extracting DOS .EXE. Copy it to a vintage box, run it, and it unpacks itself. No DOS-side tooling, no separate archiver to install on the target.

The part that doesn't exist anywhere else: the decompressor stub is built for the CPU you're aiming at. Pick a target from 8086 up to p3 and DOSKrunch ports in a depacker that uses what that chip actually has. 32-bit real-mode registers on a 386, BSWAP on a 486, an MMX block copy from the Pentium MMX up.

• Four algorithms: aplib (the default; great ratio, ~200-byte stub), lzsa2 (fastest to decompress on a 4.77 MHz 8088), lzma (best ratio, 386+ only), and stored (no compression).
• pack, unpack, and inspect. You can peek inside or extract on the host without booting DOS.
• One static binary. Install it with Cargo, or grab a prebuilt for Linux, macOS, or Windows from the releases page.

Built because nothing else produces CPU-tier-targeted DOS SFXs from a modern host.
