Version 4.18 (Chris Needham, Alistair Cree, Greg Cook)
------------
* Fixed undocumented 6502 opcodes 2B (ANC imm) and CB (ASX imm).
* Fixed memory reads in undocumented 6502 opcodes.
* Hard disk support improvements:
* Added new Select Hard Drive Folder menu option. This fixes an issue
with the "Options -> Preferences -> Save Disc/Tape/State Folders"
menu option which caused BeebEm to remember the last folder used
to open disk or tape images. This would also set the folder where
BeebEm looks for hard disk images, causing it to create empty
*.dat files in the last folder used. This change also adds a new
HardDrivePath preferences option, separate to DiscsPath.
An error is now reported if opening a hard disk image file fails.
* Improved the emulation of the teletext adapter to implement the full
range of possible states (field sync, data entry window, and video
field). The TFS ROM now acquires pages correctly.
* Fixed key selection in the User Port Breakout Box dialog.
* Fixed 1770 disk emulation to enable automatic disk density selection
in Opus DDOS.
* Fixed the Sprow ARM7TDMI co-processor emulation to ensure fetches are
word aligned.
* Removed documentation for the Emulator Traps menu option,
which has not been implemented yet.
