1732) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
174-- Need to trace over the BPM or unset the BPM
175-- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
1763) DWARF 2 support
177-- With GCC: the code must be compiled with the -gdwarf-2 option
1784) The Local and Watch variables window may display not available type information or empty information
179-- Such missing information may be included in future release
180-- The 'const' type may not be reported correctly in the DWARF information
1815) The 2MB mirroring is no longer applied in case of --dram-max option usage
1826) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted

1868) User needs to manualy check if the Atari Jaguar executable match his source code files
187-- Otherwise, source code and assembly may not match or leads to instabilities
1889) The emulator needs to be restarted in case of the following actions occur

19312) The RAM access log is limited to the 2MB
19413) In various occasions, global variables may be duplicated or without name in the DWARF information
195-- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
19614) Source code disply only assembled code from vasm with option -dwarf
19715) After a new breakpoint set, the breakpoint list window is not refreshed
198-- User must perform an operation, such code tracing, to see the breakpoints list update
19916) Some ASCII characters may be not displayed correctly
200-- It depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
202Cosmetic / UX issues
2041) The SP (Stack) icon color backgound doesn't look similar with the other ones
2052) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
2063) Not every features have associated key bindings
208Legacy issues/hints
2101) Emulator seems to have easter egg(s)
211-- The option --yarrr displays a single message and end the application
212-- Pressing F8, while in the main window, will create an extra message in the log file
2132) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
