Wanted: VIC online emulator

Kweepa · Post by **Kweepa** » Sat Nov 15, 2008 9:47 pm

It's still possible to play double size by passing a parameter to the applet, but it doesn't fit in with the pic of the TV.

I spent an hour or so trying to load a remote file, but without signing the applet (which would mean you'd have to accept a dialog before it ran - eugh) it's a pain in the arse.
I added a cross-domain policy file to kweepa.com (any .prg host would need one) but now I'm getting an access permission error connecting to *:80 connect,resolve. I'm not sure if it's fixable (although I can run an applet that loads images cross-domain when there's a cross-domain policy file on the server).
Any one got any ideas?

Kweepa, the screen emulator inside the retro-tv set is simply lovable! I want a similar one in my web site!

I've used the emulator a little bit, and I'm glad too see it's improved since last time I've used it. Anyway I am still not able to use all the keyboard keys, like punctuation, run-stop restore, and so on. Is there any special thing I should be aware of? (consider I'm using an italian keyboard layout).

Also, a question about the java code: is there any room for speed improvement? To your knowledge, is there any bottleneck in the code that can be improved, or has the code reached its theorical limit ? I'm just curious.

You guys read the news from Google today?
Should make playing emulator stuff much easier from a web browser..

Yes, my first reaction was "JarVIC is dead"!

nippur,
The bottleneck is the rendering code. It could be made faster at the expense of memory by creating lookup tables, that would have to be regenerated if for example the screen X or Y origin was changed.
I could speed it up a lot if I reduced the timing accuracy by drawing 8 pixels at a time, which mightn't be a bad idea as it's not too accurate anyway for some reason (probably VIA related).

I'm not sure about the keyboard problem. JaC64 doesn't support Italian keyboards but I don't know about RUN STOP/RESTORE - I don't think this works with a US keyboard either.

any updated on the JarVic project? is source code still available for download?

BTW, since Silverlight (flash player clone by Microsoft) is going to become the new web standard for the future, we should have a VIC-20 emulator for it too. Do you think it's possible to convert JarVic so that it compiles in Visual Studio?

Out of curiousity, is there any chance of this being used offline with the choice of my games?
