There's a Commodore 64 in your phone
JME C64 is an emulator of the once very popular home computer / game console Commodore 64 for use on mobile phones.
The speed of the original C64 is emulated, so that games don't run too fast. Note that the C64 had a 1 megahertz CPU, so even though emulating the 65xx processor in Java takes many cycles, any mobile phone should be able to run it at the right speed.
It even scales the C64 screen to fit the phone display, and it emulates the external floppy drive etc, so it's very close to the real thing, yet much smaller of course.
As JME C64 fully emulates the CPU and other hardware of the C64, the original system software is used, with permission from Commodore. Emulating the audio chip (at the time quite advanced) can't have been very simple, but it does that too.
The reason this at all makes sense is the vast amount of C64 games. You can easily find many openly advertized sites that provide such games.

A small correction: The C64 had a 1 mega-hertz CPU, not a 1 megabyte CPU.

You're of course right. Me bad :).
And it had 64 KB or RAM, where normally only 32 KB was accessible. At the time that was considered huge.

I installed this on my Nokia N95 & it runs like a dog even with sound emulation turned off & skipping frames. As a result its not really usable. Anyone have this going on an N95?
