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.

New!!! Other faster emulator appeared. Look down at Other emulation.

For a newer PC this works ok.

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.
