SpecEmu v3.4 build 2025.08.31 is released. SpecEmu is a Spectrum emulator designed to run under Windows 95/98/ME and requires DirectX installed. It has been written in 100% assembler to give it the power to accurately emulate all of the native ZX Spectrum hardware.

SpecEmu Changelog:
Fixed +3 contention issue when leaving 64K RAM mode. (thanks, r-lyeh).
Fixed Sinclair 1+2 joystick port behaviour on the Spectrum +2. (thanks, XoRRoX).
Clicking a register label, other than IM, in the debugger highlights its address in yellow in the memory viewer (suggested by XoRRoX).
Clicking the IM label in the debugger shows the disassembly for the current interrupt service routine in the current interrupt mode.
Fixed a +3 disk controller bug affecting multisector transfers.
Added an invert tape polarity option in tape options.
Added options to create new ZX Spectrum +3 (180K/360K/720K) and new Beta Disk (160K/320K/640K) image files to the File menu.
Added mouse position to character position to the Tools window (suggested by XoRRoX).
Added /bpc command line argument to add a conditional breakpoint (eg: /bpc "hl=5 a=#0d").
Added slowmo command to the debugger to slow down screen drawing and show how it's being updated (toggles on/off with the command or on reset/loading snaps).
