roadroller VS stackie

Crinkler [1] is a popular compressor-linker for 1--8 KB demos and its decompressor (partially embedded in a PE header) is probably around 1--200 bytes. Later efforts like oneKpaq [2] also have a comparable decompressor size.

If you don't mind a shameless plug and a slightly larger decompressor (about 500 bytes in JS) for better compression, my Roadroller [3] might fit the bill as well.

Roadroller [1] is probably a borderline general purpose compression algorithm, and with some automatic parameter tuning it results in 12,170 bytes estimated [2], at the expense of a lot of memory. "Estimated" because the algorithm was originally meant to be recompresssed in a ZIP file, so it doesn't bother to generate the smallest JS file in terms of uncompressed size (yet).

And compressed final code even more with Roadroller (reduced 1.3 KB in the zip). And used ECT to recompress the zip (reduced 300 KB).

I'm honored that Q1K3, in addition to many other entries to js13kGames 2021, is compresed with Roadroller [1], which is the reason that its source code is basically a random-looking string plus some bit of JS code.

I like the idea of TTT. When I discovered the JS13k I made a Texture generator ( https://github.com/Lerc/stackie ) with for a game that I never quite got around to. I didn't make that game but I have used Stackie in a heap of projects.

Mine came in at a whopping 2k but could generate some very nice stuff from compact strings.

Looking at the different approach of TTT. I wonder if I could rip out the core of Stackie that makes a (x,y)=>number and add it as a layer to TTT.
