Second Reality running in JavaScript

category: offtopic [glöplog]
To be more accurate, Second Reality running in JavaScript port of DOSBox - retropcdemos.appspot.com. No sound yet and it only runs well in Chrome browser. DOS software compatibility not so good, still working on it. Performance wise the emu can run Doom - jsdosbox.appspot.com

And goodness me what an achievement - although it is terribly slow, on my laptop (1.73ghz quadcore i7) it's doing about 2-3fps running Doom in half resolution, slightly windowed, so I'm expecting it's probably equivalent to something like a 486sx clocked at 16mhz (or even less!). Rather inefficient you could say, but nonetheless neat!

Naclbox is pretty good though, if you're a Chrome type. :)

Too slow. No, it's not 486sx. I would run Doom at more than 3 fps in a 386 then, in big window.

Ekk, there goes the daily bandwidth quota. If you get an error message, that's the reason.

Second Reality without sound is like jazz without bass.

Another major step in slowing down dosbox!

JavaScript port of jDosbox which is itself a port of DOSBox.
Built with the assistance of Google Web Toolkit (GWT).
source: http://sourceforge.net/p/jsdosbox/code/5/tree/src/

Looks more like a Java transcompiled to JavaScript kind of port rather than a "tons of sweat and love" kind of port. Both have pros & cons.

I definitly prefer the "tons of sweat and love" way of doing it that a not so interesting port of emulator...

Adapting the dynamic core to generate Js for eval() from hot code blocks will increase the % of 'pure' JavaScript.

Honestly no idea why people do this. And what skrebbel said.

it's stupidity redefined. guess someone could stash it in nacl some day, but even that. pweh.

It may be slow and semi-broken, but consider what it means: one day instead of shitty youtube links, we'll get the same convenience but get to watch the demo itself. Back to realtime! No more fucking around with emulators, just click on the link and a pre-configured emulator fires up and starts the demo...

I proposed that here for GB/GBA and NES and nobody seemed really enthusiastic about it...

Plus DOSBox is in fact NOT able to emulate everything (especially really old stuff with lots of hardware trickery) correctly. Don't fool yourself into thinking you just drop a demo in there and it'll run. Again experience from my capturing adventures...

That has already been done.

rare: true, but then not everything captures right either. And it's not just dosbox, but all emulators - meaning we'll get at least a fairly wide range of prods running.

As to it being popular, i suspect it might be a case of 'build it and they'll come'. If it's on the prod page, and you have a choice of youtube or jsemu or whatever, and the emu is reliable, better, and lower bandwidth it'll be an easy choice.

Start accepting the world turning to video. It will happen. real time is dead, long live video!

WE'RE GOING GENERIC!
