jsMSX - the first MSX Emulator written 100% in Javascript

hello all. some comments:

ARTRAG: I'm thinking about implementing a fallback mechanism in jsMSX 0.9.2 to support drawing on javascript canvas without using the high performance get/putImageData() functions (they are due only in the next generation browsers such as Firefox 2.0, still in beta). It boils down to using function calls (moveto()/lineto()) instead of a direct array access, and I believe it will impact performance. However, after this modification you should be able to run jsMSX on current mainstream browsers such as Firefox 1.5, Opera 9.0, and even Internet Explorer 6.0 (with google's IE canvas plugin) - albeit a bit slower.

mars2000you: it's possible to run it offline if you sign the javascript code. I believe that it could also run offline from inside a XUL application making use of jsMSX.

DTail: indeed, I was thinking about creating a jsOpenMSX and a jsBlueMSX. what do you think?

But does it run Linux?

Very impressive and fun Well done mrcgran. Do you know if a modern high end PC is able to run it at full speed? My laptop doesn't get even close, but its almost two years old.

it'll end up with Nyyrikki coding an MSX1 emulator for turboR in obfuscated MSX-BASIC. Mark my words! ^_^.

why not an MSXturboR emulator for MSX1?

I think I'll have access to a better one soon and I'll give it a try on that machine.

In any case its really cool to see an MSX emulator in javascript. I like playing javascript demos and some are really stunning. jsMSX is another proof that its possible to do something complex with decent speed in a simple scripting language like javascript.
