Known issues\r
============\r
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\r
2) The BPM (Breapoint) remains stuck on his address when user wants to continue the code execution\r
-- Need to trace over the BPM or unset the BPM\r
-- The issue can be prevented if the code doesn't set IRQ, otherwise the IRQ will need to be traced to get back control\r
3) To support DWARF 2\r
-- With GCC: the code must be compiled with the -gdwarf-2 option\r
4) The Local and Watch variables window  may display not available type information or empty information\r
-- Such missing information may be included in future release\r
-- The 'const' type may not be reported correctly in the DWARF information \r
5) The 2MB mirroring is no longer applied in case of --dram-max option usage\r
6) Stack must reflect the --dram-max option usage otherwise the stack may be corrupted\r
-- The application needs to set the SP (Stack) in accordance\r
7) The Exception Vector Table window displays only 65 vectors\r
-- Missing vectors may be added in future release\r
8) User needs to manualy check if the Atari Jaguar executable match his source code files\r
-- Otherwise, source code and assembly may not match or leads to instabilities\r
9) The emulator needs to be restarted in case of the following actions occur\r
-- Key bindings changes\r
-- BIOS selection changes and without new executable load\r
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\r
11) Emulator will crash in case of wrong address value provided in the memory browser\r
12) The RAM access log is limited to the 2MB\r
13) In various occasions, global variables may be duplicated or without name in the DWARF information\r
-- It may come from the Vlink linker and/or GCC 7.1.0 or 8.2.0 compilation with -gdwarf-2 option\r
\r
Cosmetic / UX issues\r
====================\r
1) The SP (Stack) icon color backgound doesn't look similar with the other ones\r
2) The SP (Stack) browser size always open at a forced size no matter if the size has been changed\r
3) Not every features have associated key bindings\r
\r
Legacy issues/hints\r
===================\r
1) Emulator seems to have easter egg(s)\r
-- The option --yarrr displays a single message and end the application\r
-- Pressing F8, while in the main window, will create an extra message in the log file\r
2) The --alpine option force the log file but it can be override if --no-log option is set after the --alpine option\r
\r
Project information\r
