ZEsarUX v6.1 Beta (2018/04/13) is released. ZEsarUX is a ZX Machines Emulator for Unix, including: ZX Spectrum ; ZX-Uno ; ZX80 ; ZX81 ; Z88 ; Jupiter Ace ; Chloe 140 SE, Chloe 280 SE ; Prism ; Timex TS 2068 ; Amstrad CPC 464. ZEsarUX is Open-Source and runs on Windows, Mac OS X and Linux.

ZEsarUX Features:
Added ZX-Evolution BaseConf emulation (experimental)
Added a fast spectrum core (with some features disabled) just for slow devices, like Raspberry Pi 1/Zero. Now ZEsarUX is playable on RPi1/Zero again!
Added setting to save spectrum screen to pbm file (black&white)
Added a setting to dump ram contents to file when exiting ZEsarUX, ideal to run automatic tests

Improved debugging:

added cpu-step-over function on debug menu (was already available from ZRCP)
added function to write byte to file on ZEsarUX hardware debug ports
Improved ZRCP:

when a breakpoint is fired on cpu-step-mode, the breakpoint condition is shown on ZRCP
Improved file viewer from file utilities:

conversion utility
Improved TSConf emulation:

added TR-DOS emulation support
Improved menu interface:

added a setting to limit menu event: enabling it you should press the menu key 3 times in a second to open the menu
added a setting to hide directories from file selector menus, useful when you don't want the user to be able to navigate the filesystem
Improved TBBlue emulation:

Added Copper
Added almost all next extended opcodes
Added a setting to start TBBlue directly to a 48 rom but with all the Next features enabled, useful for fast snapshot loading
Fixed panic screen: now it is shown on all machines. New design. I hope you never see it ;)
Fixed bug on Z80 cpu core, iff2 was not being reset to 0 when firing an interrupt, so reading it by using LD A,R and LD A,I affected many demos
