Phi2x updated his JavaScript Amstrad CPC emulator and did a major overhaul of the emulation engine. It is now a cycle-exact emulation which means that it is prepared for the latest games and demos. To use the emulator, just go to http://www.cpcbox.com and let your browser do all the magic.

CPCBox 20120327 changelog:

  • Added a settings panel
  • Implemented monochrome monitor rendering
  • Implemented floppy drive B support
  • Implemented 512KB RAM extension

Some days ago, an update to CPCBox, a JavaScript CPC emulator, brought sound emulation to the emulator and now the second JavaScript emulator, Roland by Antonio Villena, features sound emulation, too. When I tested it, it seems a bit smoother than the sound emulation in CPCBox, so you should try it by yourself (use Firefox) on http://roland.antoniovillena.es/.

If you want to discuss the emulator, have at look at this thread in the CPCWiki forums.

Today is the “World Music Day” and Phi2x decided, that the best way to celebrate it is a new release of his JavaScript CPC emulator “CPCBox”. Here is the announcement (thanks for keeping me informed about this update :-)):

“There is something new with CPCBox, the Amstrad CPC emulator in Javascript!
Since its release last year, a lot happened.
Over time, I improved emulation accuracy, made optimizations to be more swift, support for disk images, and many more.

Today, to celebrate the “World music day”, CPCBox went above and beyond.
Yep, the new version of CPCBox brings the lovely sound chip emulation of the Amstrad.
It’s ideal for listening to chiptunes and set back into the mood of 80’s geeks.

Technically speaking, sound datas are output through Mozilla Audio Data API. It implies that, as of now, it’s necessary to use Firefox to enjoy sound in CPCBox.
For a nice relaxing time in Arkanoid, Boulder Dash or Gryzor, only one address to go: http://www.cpcbox.com

Today I got a mail (thanks :)!) about a new CPC emulator entirely written in JavaScript. The new emulator is called CPCBox and you can test it on http://www.cpcbox.com. Currently it is best viewed with Google Chrome, but it also worked with Firefox on my system (Opera 10.61 didn’t work). Currently the emulator only loads Snapshot and doesn’t play sound, but hey – this is the first CPC emulator written in JavaScript. The emulator was written from scratch and is mainly an experiment to push HTML5 to it’s limits, but the author wants to improve it in the future.
