203 Known issues
204 ============
205 1) 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
206 2) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
207 -- Need to trace over the BPM or unset the BPM
208 -- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
209 3) DWARF 2 support
210 -- With GCC: the code must be compiled with the -gdwarf-2 option
211 4) The Local and Watch variables window may display not available type information or empty information
212 -- Such missing information may be included in future release
213 -- The 'const' type may not be reported correctly in the DWARF information
214 5) The 2MB mirroring is no longer applied in case of --dram-max option usage
215 6) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted
216 -- The application needs to set the SP (Stack) in accordance
217 7) The Exception Vector Table window displays only 65 vectors
218 -- Missing vectors may be added in future release
219 8) User needs to manualy check if the Atari Jaguar executable match his source code files
220 -- Otherwise, source code and assembly may not match or leads to instabilities
221 9) The emulator needs to be restarted in case of the following actions occur
222 -- Key bindings changes
223 -- BIOS selection changes and without new executable load
224 10) 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
225 11) Emulator will crash in case of wrong address value provided in the memory browser
226 12) The RAM access log is limited to the 2MB
227 13) In various occasions, global variables may be duplicated or without name in the DWARF information
228 -- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
229 14) Source code disply only assembled code from vasm with option -dwarf
230 15) After a new breakpoint set, the breakpoint list window is not refreshed
231 -- User must perform an operation, such code tracing, to see the breakpoints list update
232 16) Some ASCII characters may be not displayed correctly
233 -- It depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
234 17) Potential legacy crash when leaving emulator in pause mode for a long period of time
236 Cosmetic / UX issues
237 ====================
238 1) The SP (Stack) icon color backgound doesn't look similar with the other ones
239 2) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
240 3) Not every features have associated key bindings
242 Legacy issues/hints
243 ===================
244 1) Emulator seems to have easter egg(s)
245 -- The option --yarrr displays a single message and end the application
246 -- Pressing F8, while in the main window, will create an extra message in the log file
247 2) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
