A novel take on lossless data compression

Crinkler is an executable file compressor (or rather, a compressing linker) for compressing small 32-bit Windows demoscene executables. As of 2026, it is the most widely used tool for compressing 1k/4k/8k intros.

LZSSE compression codec ported to SIMDe

Simple PE32 Packer with aPLib compression library. I checked that this packer works on the program LinkParser.exe. This code must be compiled in release mode in order to work properly. I don't know the reason why. Sorry...
