BeebEm Change History

=====================

 

Version 4.01 (Steve Pick, Mike Wyatt)

-----------------------------------------------------

* Rewrote debugger command interpreter:

- Supports command names longer than one character

- Added command history (up/down arrows when command box focused)

- Commands are now implemented using function pointers, should be more expandable.

- More descriptive help - type 'help', 'help ' or 'help '.

- Better label support - any word in command arguments preceded with a '.' is interpreted as a label and resolved before the args are passed to the command handler.

* Fixed bug that prevented checkboxes enabled/disabled by command from actually taking effect.

* Expanded debug memory map support:

- Maps can now be stored for each ROM, just put a .map file with the same name as the ROM in the ROM's directory, for example BeebFile\BBC\os12.map corresponds to BeebFile\BBC\OS12.ROM, and address queries (via 'help ') will return info from the currently selected ROM's map.

- Address info queries now understand shadow/private/sideways RAM in different machines.

- Cleaned up MemoryMap.txt and moved it to BeebFile\BBC\OS12.map

* Added 'state m' command to get state of memory (ACCCON and Shadow/Sideways RAM info)

* Added routines for extracting header info from paged ROMs, and 'state r' command to dump this info in the debugger.

* Break now shows previous Program Counter address as well as the current address. This is useful for finding where the source of a jump was.

* A bit of a hack to allow debug window to go behind main window, but also come to foreground with main window.

* Added option to enable DirectX smoothing when only in teletext mode.
