221
222 Known issues
223 ============
224 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
225 2) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution
226 -- Need to trace over the BPM or unset the BPM
227 -- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control
228 3) DWARF 2 support
229 -- With GCC: the code must be compiled with the -gdwarf-2 option
230 4) The Local and Watch variables window may display not available type information or empty information
231 -- Such missing information may be included in future release
232 -- The 'const' type may not be reported correctly in the DWARF information
233 5) The 2MB mirroring is no longer applied in case of --dram-max option usage
234 6) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted
235 -- The application needs to set the SP (Stack) in accordance
236 7) The Exception Vector Table window displays only 65 vectors
237 -- Missing vectors may be added in future release
238 8) User needs to manualy check if the Atari Jaguar executable match his source code files
239 -- Otherwise, source code and assembly may not match or leads to instabilities
240 9) The emulator needs to be restarted in case of the following actions occur
241 -- Key bindings changes
242 -- BIOS selection changes and without new executable load
243 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
244 11) Emulator will crash in case of wrong address value provided in the memory browser
245 12) The RAM access log is limited to the 2MB
246 13) In various occasions, global variables may be duplicated or without name in the DWARF information
247 -- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option
248 14) Source code disply only assembled code from vasm with option -dwarf
249 15) After a new breakpoint set, the breakpoint list window is not refreshed
250 -- User must perform an operation, such code tracing, to see the breakpoints list update
251 16) Some ASCII characters may be not displayed correctly
252 -- Probably depend how the text is displayed, this is related to the Qt/HTML encoding done when reading DWARF file
253 17) Potential legacy crash when leaving emulator in pause mode for a long period of time
254 -- Need much investigation
255
256 Cosmetic / UX issues
257 ====================
258 1) The SP (Stack) icon color backgound doesn't look similar with the other ones
259 2) The SP (Stack) browser size always open at a forced size no matter if the size has been changed
260 3) Not every features have associated key bindings
261
262 Legacy issues/hints
263 ===================
264 1) Emulator seems to have easter egg(s)
265 -- The option --yarrr displays a single message and end the application
266 -- Pressing F8, while in the main window, will create an extra message in the log file
267 2) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option
268
269 Project information
