Zip-tool

Browser webassembly extractor demos that work, born from a chat with Claude AI.

7z-wasm extracts and compresses. Claude made it from git.
Supports: .7z .zip .tar .gz .bz2 .xz .rar .zst and more. Maybe.

archive-wasm extracts in this demo only. It is based on git
and supports, as it says: .zip .7z .tar .gz .bz2 .xz .zst .rar .cab .iso and more.

Grok made these Javascript tools. Not sure on large files.

fflate It extracts zip files, maybe compresses too. Grok made it from git.

JSZip based on git.

Image sharp colors tool

Here is a

SharpTool

created by Gemini that helps in making sharp colors for images.

Source is a small blurred .jpg

As result, a large four colors image

And this is after slight paint fills in MS Paint.

---

To remove background and make image transparent, there is

TransparentTool

created by Gemini. Bordered paint fill makes the work much easier than it looks.

A simple sketching

DrawTool

created by Gemini. Not so much as Paint. Anyway, can draw ideas for AIs to improve their imagination. Usable at pixeling level, if needed.

CopyTool

provides some basic copy paste options, move, flip, rotate, append images (preps. for AI)

---

SplitSprites

tool helps in sprites splitting process. AI created images need to be prepared for javascript. AI generated mouse in various positions (by using templates and mouse initial image) is made by using these tools only + various AI support. Colors reduction, placement, various flip, move and copy manipulations. Transparency and big large image of sprites appending to each other. AIs love 1024x1024 (or 2048x2048) image manipulations. Pure vibecoding.

Webassembly Canvas rendering

A simple .c compiled to webassembly

 "Hello World" sample,  to see it working and debug in browser Developers tools https://chessforeva.codeberg.page/wasm/canvas_render.htm

The same in webworkers, means threaded less browser consuming, can be in background.

C&C DOS in browser

Nope. It still doesn't work correctly. Too much lags.

Anyway, if You decide to give it a try then do not panic while downloading 19mb webpage on startup.

Thanks to Webassembly and js-dos team for the DOS emulator based on well known DosBox.

And Westwood Studios (wiki), of course, all the thanks and bitcoins.

And Netlify as the hoster site.

So, this version contains list of user-created maps (on Load Mission),

 with glitches too, but interesting to play.

Mostly playable by mouse.
Known keys, as I remember, were:
H - home at Construction yard
Shift+ left mouse - select multiple units
Ctrl+ 1, or 2, or 3, or... - assign key to selected units
Then just press 1, or 2, or... and send units by mouse
G - set unit to guard area

There are videos on how to play -on youtube.

Other emulation:
Download cc.zip and drop it to the https://www.neilb.net/doswasmx/ site.
Run a.bat, then c.bat
Works fast.
