From the same game developer who brought us the popular Cauldron Remake, comes a JavaCPC Emulator by DevilMarkus. The Amstrad CPC was a home computer popular in Europe and that came out about the same time as the Commodore 64. You can find out more about the Amstrad CPC at Wikipedia.

Note that you have to always press the reset button located under each game when changing or leaving a page to avoid sound issues.

You can also download a portable version of the Amstrad CPC emulator from the same developer. It can be downloaded here: http://sourceforge.net/projects/javacpc.
