What's New:
Fixed NMOS 6502 instructions 6B (ARR imm) and EB (SBC imm).
Fixed timings for instructions 83 (SAX (zp,X)), 8F (SAX abs), B3 (LAX (zp),Y), and BB (LAS abs,Y).
Fixed 65C12 instruction timings for ADC and SBC in decimal mode, ASL, LSR, ROL, ROR, and BRA.
Added keyboard shortcuts for changing text-to-speech reading rate. Enable text output reader by default when text-to-speech is enabled.
Fixed crash in the debugger, where sideways RAM does not contain a normal ROM image.
Fixed Econet source code cross-compatiblity issue.
Serial and tape emulation improvements:
* Fixed serial transmit state: Writing a master reset to the ACIA control register should stop transmitting data. This was causing extra bytes to be written to UEF files when saving to tape.
* The Tape Control dialog Record button now always prompts the user to create a new UEF file, rather than appending to the currently open UEF file. This change also fixes a bug where the button would do nothing if a CSW file was loaded.
* Opening the Tape Control dialog no longer causes Block? or Data? errors during loading.
* The BeebEm version number is now stored in UEF tape files.
Fixed Master real time clock year handling. The year is stored as the last two digits. Removed the "Master 128 RTC Y2K Adjust" option. Note that the Master MOS still displays years as 19xx, but will accept any century when setting the time using TIME$.
Added debugger support for the BBC Master real-time clock and CMOS RAM.
Added a new Music 5000 disk image (M5000-4.ssd) that uses a different copy protection patch, to fix the staff editor.
Added ZipFile project, to create BeebEm.zip distribution. The project runs a Perl script, so requires a working Perl installation.
The Write Protect On Load menu option is now also applied to files loaded from the command line.
Improved the Disc Export dialog, which now detects and avoids using file names that are not valid on the host filesystem. The dialog box allows you to double-click an entry to rename files.
The BeebEm window on Windows 11 is now drawn with rounded corners disabled.
