What is YAPE?

YAPE is a Commodore 264 family emulator. It's an 8-bit microcomputer
family from the once-great-now-defunc Commodore Business Machines Ltd.
They were released as a successor to the immensely popular Commodore 64
supposedly to either compete with the ZX Spectrum or other micros but
eventually failed to gain market success and the whole line was dumped
within a couple of years. However they were hugely popular in a few
countries such as Hungary, Germany or Italy (to a certain extent also
in the UK).

The program features an accurate cycle-exact approach and a high
level of emulation. The user interface aims to exploit the potentials
of the Windows operating environment. The emulator is written in C++
and is compiled with MS Visual C++. There's an older port to other
platforms than Windows (using the SDL
library). In the future there'll probably be other ports made.

YAPE was born out of a disassembler project during the summer of
2000 and had been for some time the only actively updated Commodore 264
family emulator. See the Changes.txt for development and release
milestones.

Minimum system requirements

Since YAPE is a cycle-based emulator (much like the Commodore 64
emulators Hoxs or Frodo), its system requirements are higher than that
of other line-, instruction- or event-based emulators. In return however, it makes
development easier for me while providing maximum possible accuracy. For
attaining 100% relative speed to the original hardware, you need:

PII 333 MHz or higher without sound and true drive emulation.

PII 500 MHz or higher for both sound and true drive emulation.

8 MB VGA card capable of DirectX 3.0

Sound card (DirectSound compatible)

Windows 9x, 2000/XP (and NT 4.0 without sound)
