sleepdart

A half-hearted attempt at writing a reasonably accurate ZX Spectrum emulator.

See it in action:

• "Shock" megademo
• DIZZZRUPTOR
• New View 48K

Features

• Mostly cycle-accurate Z80 emulation, including contention and fetch/write timings
• Sub-frame accuracy for ULA draws
• Tape (.tap file) support with basic hooks for fast/automated loading
• Beeper sound
• AY-3 sound (based on ayumi library)
• Reasonably fast (typically ~3500 FPS uncapped on an i3-4150)
• Keyboard input
• SZX state loading
• Adjustable palettes
• More to come...
