PyZX is a ZX Spectrum emulator written entirely in Python. It is based on Vadim Kataev's PyZX Python Spectrum Emulator and is licensed under the GPL-2 license.

• Python 3.x (available at python.org)
• PyGame 1.7+ (available at pygame.org)

To run the emulator, use the following command:

python3 spectrum.py

Optionally, you can use the -OO optimization flag for potentially better performance:

python3 -OO spectrum.py

• Ctrl + Alt: Switch to special mode
• Alt + AnyKey: Symbol shift
• Ctrl (in normal mode) + AnyKey: Big/small characters
• Ctrl (in special mode) + AnyKey: Symbol shift 2

Thanks to Jasper (spectrum.lovely.net) for the excellent Java emulator of the ZX Spectrum. A significant portion of the code was automatically translated from Java to Python, and further optimization and rewriting are needed to improve emulation speed.

• Implement a more Pythonic approach for the core (Z80 CPU)
• Add threading for parallel processing (video and possibly keyboard)
• Support for TAP/TZX files

• Vadim Kataev (initial version)
• Stanislav Yudin (initial conversion to Python 3)
