Version 1.6 - 27-Oct-2025 by wavemotion-dave
- Revamped Z80 CPU core to provide more accurate timing and memory contention/floating bus. Multi-color games (aka Nirvana+, BiFrost, etc) now play and look reasonably correct and CPU speed is generally correct.
- Fix for AY music not restoring properly on some Load States.
- Smoother beeper sound for improved fidelity.
- Added Kempston 2nd Fire button which can be mapped in.
- Default machine is now the ZX Spectrum 128K but it will revert to 48K for common games with compatibility issues.
- Other minor cleanups and improvements as time permitted.
