b2 Changelog:
Debugger Enhancements:
Initial support for symbols in debugger, thanks to Mark Fisher.
Breakpoints in I/O regions are now supported.
Memory-mapped I/O can now be viewed in memory and disassembly dialogs.
Fixed the debugger’s ROM view when using BBC B without a ROM board.
Work on symbols support is ongoing.
UI Improvements:
The GUI Font Size setting has been replaced with a general GUI Scale; you’ll need to set this up again as a one-time change. Apologies for the inconvenience!
(macOS/Windows) Enhanced support for retina/high-DPI displays, resulting in a significantly improved appearance.
Native file dialogs have also been improved: they now handle suggested paths better, remember the previous folder, and include file extensions.
(For Linux users with high-DPI displays, adjust the GUI scale to your preference, as auto-detection of a sensible value is challenging for b2.)
Emulation Updates:
Resolved issues with the 1770 FDC: fixed both Watford DDB2/DDB3 double density and general issues with Watford DDB2.
Corrected the video ULA address range.
