212
213 Known issues
214 ============
215 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
216 2) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
217 -- Need to trace over the BPM or unset the BPM
218 -- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
219 3) DWARF 2 support
220 -- With GCC: the code must be compiled with the -gdwarf-2 option
221 4) The Local and Watch variables window may display not available type information or empty information
222 -- Such missing information may be included in future release
223 -- The 'const' type may not be reported correctly in the DWARF information
224 5) The 2MB mirroring is no longer applied in case of --dram-max option usage
225 6) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted
226 -- The application needs to set the SP (Stack) in accordance
227 7) The Exception Vector Table window displays only 65 vectors
228 -- Missing vectors may be added in future release
229 8) User needs to manualy check if the Atari Jaguar executable match his source code files
230 -- Otherwise, source code and assembly may not match or leads to instabilities
231 9) The emulator needs to be restarted in case of the following actions occur
232 -- Key bindings changes
233 -- BIOS selection changes and without new executable load
234 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
235 11) Emulator will crash in case of wrong address value provided in the memory browser
236 12) The RAM access log is limited to the 2MB
237 13) In various occasions, global variables may be duplicated or without name in the DWARF information
238 -- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
239 14) Source code disply only assembled code from vasm with option -dwarf
240 15) After a new breakpoint set, the breakpoint list window is not refreshed
241 -- User must perform an operation, such code tracing, to see the breakpoints list update
242 16) Some ASCII characters may be not displayed correctly
243 -- Probably depend how the text is displayed, this is related to the Qt/HTML encoding done when reading DWARF file
244 17) Potential legacy crash when leaving emulator in pause mode for a long period of time
245 -- Need much investigation
246
247 Cosmetic / UX issues
248 ====================
249 1) The SP (Stack) icon color backgound doesn't look similar with the other ones
250 2) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
251 3) Not every features have associated key bindings
252
253 Legacy issues/hints
254 ===================
255 1) Emulator seems to have easter egg(s)
256 -- The option --yarrr displays a single message and end the application
257 -- Pressing F8, while in the main window, will create an extra message in the log file
258 2) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
259
260 Project information
