190Known issues
191============
1921) 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
1932) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
194-- Need to trace over the BPM or unset the BPM
195-- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
1963) DWARF 2 support
197-- With GCC: the code must be compiled with the -gdwarf-2 option
1984) The Local and Watch variables window may display not available type information or empty information
199-- Such missing information may be included in future release
200-- The 'const' type may not be reported correctly in the DWARF information
2015) The 2MB mirroring is no longer applied in case of --dram-max option usage
2026) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted
203-- The application needs to set the SP (Stack) in accordance
2047) The Exception Vector Table window displays only 65 vectors
205-- Missing vectors may be added in future release
2068) User needs to manualy check if the Atari Jaguar executable match his source code files
207-- Otherwise, source code and assembly may not match or leads to instabilities
2089) The emulator needs to be restarted in case of the following actions occur
209-- Key bindings changes
210-- BIOS selection changes and without new executable load
21110) 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
21211) Emulator will crash in case of wrong address value provided in the memory browser
21312) The RAM access log is limited to the 2MB
21413) In various occasions, global variables may be duplicated or without name in the DWARF information
215-- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
21614) Source code disply only assembled code from vasm with option -dwarf
21715) After a new breakpoint set, the breakpoint list window is not refreshed
218-- User must perform an operation, such code tracing, to see the breakpoints list update
21916) Some ASCII characters may be not displayed correctly
220-- It depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
24470541 22117) Potential legacy crash when leaving emulator in pause mode for a long period of time

222
223Cosmetic / UX issues
224====================
2251) The SP (Stack) icon color backgound doesn't look similar with the other ones
2262) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
2273) Not every features have associated key bindings
228
229Legacy issues/hints
230===================
2311) Emulator seems to have easter egg(s)
232-- The option --yarrr displays a single message and end the application
233-- Pressing F8, while in the main window, will create an extra message in the log file
2342) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
235
