Release 5 (TBA) --------------- 0) Added a date creation stamp in the application command line information - This date already appears in the Release 4 executable but was not referenced in his history note 1) Added a specific breakpoint for the M68K illegal instruction exception -- Alert box will display a message and then the code will stop 2) Added a specific breakpoint for the M68K address error exception -- Alert box will display a message and then the code will stop 3) Added a HW registers browser window and set a tab for the Blitter 4) Added detection for the unsigned/signed short type -- Will allow the return of a short type variable's value 5) Added a specific breakpoint for the M68K Unimplemented instruction, and Exception not referenced exceptions 6) Fix potential emulator freeze after an exception has occured 7) Fix a random crash when reading the source lines information 8) Added ELF & DWARF .debug* types 9) Added ELF section types check and new error messages 10) Project

breakpoint for ROM cartridge or unknown memory location writing Release 4 (10th August 2019) ---------------------------- Git commit: 9b25d85d1ea4a9476b83476bcec65e05464f68da - 0) The zoom value setting has been fixed in the registry 1) Debugger mode now shares the same alpine rom path setting 2) Local variables window displays register name now 3) Switch to Zlib 1.2.11 static library 64bits for VS 2017 4) Switch to SDL 1.2.15 static library 64bits for VS 2017 5) Local variables window displays values from function's parameters 6) Fixed the typedef's name display in Local and Watch variables window 7) Breakpoint may now occur in case of a ROM cartridge writing -- ROM cartridge writing detection follow the alpine "allow writes to cartridge rom"'s flag check -- Alert box will display a message with possibility to pass or not the breakpoint only if this is related to a 8 or 16 bits ROM access 8) Local variables window detects now if a variable is used or not by the code 9) The address provided in the debugger memory windows is now verified to prevent crash -- Wrong address will be displayed in red 10) UI changes -- Added new icons for the exit and status features -- Modified icons for the SP (Stack) browser -- Unified icons sizes depend on their usage (drop down menu and main menu) -- Underline the active M68K line in the disassembly window -- Allow the up/down navigation on the SP (Stack) browser -- Restart function cleans-up the SP (Stack) browser and the heap allocator system -- Fixed the up navigation on the memory window 11) Added some log information for the emulator initialisations 12) Breakpoint will happen in case of writing at unknown memory location -- Alert box will display a message and then the code will stop 13) Added the DRAM size in the emulator status window 14) Debugger sources code clean-up 15) Added a call stack feature 16) Follow platform requirement to prevent source file reading issue 17) UI modifications -- Modified icon for the memory window to make a distinction with the memory browser -- The all watch, and Exception Vector Table windows, can be closed using keyboard -- Renamed the debugger dedicated icons to make a distinction -- Added the call stack window 18) Fixed a crash in the all watch window after loading a new binary without ELF/DWARF information -- Previously used ELF/DWARF information was still accessible 19) Fixed slash/backslash issue, in the Alpine tab, to follow platform requirement 20) Heap allocation window uses the DRAM size limit option and detect if heap allocation shares space with SP (Stack) 21) Added a Jaguar model and BIOS configuration tab 22) Jaguar model and BIOS configuration integration 23) Added LEB128 decoding functions -- It is used for the DWARF decoding information

key binding 27) Minor misspellings fixes 28) DWARF source code directory path clean-up 29) Added a source code files list viewer -- List comes from the DWARF information 30) Check potential variables missing/incomplete description found in the DWARF information -- No crash involved but can help to reduce such as variables duplicate or the blank ones 31) Added a sorting filter in the all watches window 32) Improve source code file reading to avoid additional text/bytes reading 33) Help & content texts updates 34) Fixed a crash legacy issue when emulator launches in Alpine mode without a valid rom 35) Added the support for the used lines source's DWARF structure -- Mostly used to handle missing subprogram's lines information, and missing CU's low/high PC 36) Added the Rx version's contact in the help text 37) Added search paths in case of missing DWARF directories information -- Used to look for the file(s) 38) Setup CU's low/high PC in case of the DWARF structures doesn't have it -- Used mostly to allow display the source assembled with vasm 39) Added function name support from ELF structure 40) Added the return address information in the call stack 41) Added multiple breakpoints feature, and their key bindings, for functions only 42) Added timer initialisation for the SDL setup 43) Added a cartridge view menu -- Added a window to display my own directory and his files list 44) Debugger sources code clean-up 45) Fix a crash when emulator, in non-debugger mode, opens the breakpoint UIs at launch 46) Fix crash with potential missing DWARF structure tag's type name 47) Added ELF sections check so a potential unknown section will stop, or not stop, the decoding 48) Project has switched to QT 5.12.0 library 64bits for VS 2017 49) Added a Save Dump As... feature to save a memory zone to a file 50) The -d command line option, dedicated to the debugger, has been renamed to avoid duplication with the dsp one -- -d has been renamed by -D because another -d was also used for the dsp command line option 51) Removed the sorting filter in the all watches window 52) Fix the support of the DRAM size limit option in the heap allocation window 53) Set cartridge view menu for debugger mode only 54) Prevent crash in case of call stack is out of range Release 3 (13th November 2017) ------------------------------ Git commit: b1b673a3b0d19e3c2c45b6590b773b11e45bced7 -

more appropriate way -- Updated the emulator application credits line 3) Added 'Rx' word to the emulator name 4) Fixed a crash when reading the DWARF information in the case of the DWARF2 format has not been used 5) Added ui, alpine and debugger groups in the settings 6) Added the possibility to erase settings 7) Added the --es-all, --es-ui, --es-alpine and --es-debugger options to erase specific settings 8) Added a key bindings tab and adapted the configuration dialog tabs -- User can modify the key bindings where appropriate -- Key bindings UI is displayed based on the option used (--debugger, -- alpine) 9) Fixed a crash, in Release mode, when the HW labels setting is turn on 10) Solved an interference between the HW labels setting and the one used by the debugger -- The setting is now only the reference used 11) Fixed the SP (Stack) browser UI potential missing data 12) Create a directory for EEPROMs (based on the EEPROMs setting) if it doesn't already exist 13) Keep the scrollbar position in accordance of the M68K PC pointer -- UI displays the source without the need to move down/up the scrollbar 14) Fixed a crash when DWARF information report a source line number exceeding the number of lines present in a source file -- This may come from the linker vlink 15) Improved the .heap section detection to avoid a detection error -- Depend vlink version, .heap section may have an Alloc flag 16) Fixed a crash when DWARF information does references to missing source code files 17) Added a local variables window 18) Project has switched to Visual Studio 2017

12) 64 bits Release executable 13) Fixed (hacking) the display of the SP (Stack) browser 14) Set the emulator in Halt mode when launched in alpine debug mode without a loaded rom -- Otherwise the 68000 program counter will have a 0 value and will execute the code at this address 15) Added some information in the --help/-h/-? option 16) --debugger option no longer force the log file 17) Added a --dram-max option to extend the DRAM size to 8MB 18) Added the "enter" key support when setting the BPM (Breapoint) 19) Save the windows positions, size and visibilities (show or hide) status -- Such
