Yeah, last time I checked there was just one ZIP handling library for Javascript, and it wasn't easy to use. But years have passed.
I tried, I can did that on .exe and android, but not to HTML5, since its inside the browser the browser thinks it's a security breach and will block the extraction.
Damn that sounded like a good idea

they are very small, the problem to merge then is the time and work required, I will need to recode the whole game.
Ouch. Fair enough.
