A whole game in a QR code and Crinkler – a demoscene compressor

MattKC asked himself if he could put a whole game into a QR code. He actually succeeds at it, but with some fascinating turns along the way which include changing linker settings and creating a window in assembly.

One of his other adventures is compressing the executable using an old demoscene tool: Crinkler. Crinkler is not your normal RAR, ZIP, or other self-extracting executable compressors. Crinkler replaces the linker used to generate the executable by a combined linker and compressor. The result is an EXE file which does not do any kind of dropping and decompresses into memory like a traditional executable file compressor.

It also uses context modelling, which produces a far superior compression ratio than most other compressors. The disadvantage of context modelling is that it is extremely slow and needs quite a lot of memory for decompression, but this is not usually a problem with 4k demos.
