Version 4.0 of Q-emuLator has been released
for Windows 7 SP1 and later.
Extensive research went into making the CPU emulation cycle-accurate (also simulating its interaction with the ZX8301 video ULA and the 8049 coprocessor), creating a new lower-level format for microdrive images and studying the hardware of the ICL One Per Desk computer (a cousin of the QL).
Q-emuLator 4 also adds emulation of the
QSound interface (3 sound channels), can run the pre-existing extended graphics
modes inside a window, includes an improved ram disk driver and has more
extensive debugging capabilities
For the nostalgic, there are monochrome
monitor colour options and simulation of the microdrive motor and tape noise.
The overall experience of running the
emulator should be smoother, with new features like default directories for
ROMs/software/configurations, reduced audio latency, a Pause command
(Windows-Alt-P), auto CPU speed setting, ability to create new empty MDV,
MDVRAW, QXL.WIN and IMG file containers.
The manual has been updated and expanded
and there are now an online troubleshooting page and a 'check for updates'
command.
