199Known issues
200============
2011) Video output is not displayed due to my OpenGL / QT5 5.5.1 integration with VS 2015 but solved when using the QT 5.9.1 package for VS 2017
2022) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
203-- Need to trace over the BPM or unset the BPM
204-- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
2053) DWARF 2 support
206-- With GCC: the code must be compiled with the -gdwarf-2 option
2074) The Local and Watch variables window may display not available type information or empty information
208-- Such missing information may be included in future release
209-- The 'const' type may not be reported correctly in the DWARF information
2105) The 2MB mirroring is no longer applied in case of --dram-max option usage
2116) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted
212-- The application needs to set the SP (Stack) in accordance
2137) The Exception Vector Table window displays only 65 vectors
214-- Missing vectors may be added in future release
2158) User needs to manualy check if the Atari Jaguar executable match his source code files
216-- Otherwise, source code and assembly may not match or leads to instabilities
2179) The emulator needs to be restarted in case of the following actions occur
218-- Key bindings changes
219-- BIOS selection changes and without new executable load
22010) In the case of a ROM cartridge writing, and with occuring breakpoint, the PC pointer will point at the next instruction and not at the instruction causing the breakpoint
22111) Emulator will crash in case of wrong address value provided in the memory browser
22212) The RAM access log is limited to the 2MB
22313) In various occasions, global variables may be duplicated or without name in the DWARF information
224-- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
22514) Source code disply only assembled code from vasm with option -dwarf
22615) After a new breakpoint set, the breakpoint list window is not refreshed
227-- User must perform an operation, such code tracing, to see the breakpoints list update
22816) Some ASCII characters may be not displayed correctly
229-- It depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
24470541 23017) Potential legacy crash when leaving emulator in pause mode for a long period of time

232Cosmetic / UX issues
233====================
2341) The SP (Stack) icon color backgound doesn't look similar with the other ones
2352) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
2363) Not every features have associated key bindings
237
238Legacy issues/hints
239===================
2401) Emulator seems to have easter egg(s)
241-- The option --yarrr displays a single message and end the application
242-- Pressing F8, while in the main window, will create an extra message in the log file
2432) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
244
