[Windows/ARM] JIT ARM32 (MSVC) support #633
Comments
Make instruction trace from your version and windows desktop desmume and check to make sure they are the same. Look to see if sound registers/video registers are being written (breakpoints in c++). |

Hi, I was compiling your emulator as libretro core (base code from this repo)
I need it in this way because it's the only solution to port DS emulation for legacy windows arm devices.
I made the required changes on memory functions and seems fine as the app didn't crash,
Issue
all I got is white screen with no sound also, seems it's waiting for something because JIT instructions are working (as per the log below),
I'm not sure if I compile it in the right way because I included only
utils/arm_jit/arm_jit_arm.cpp
which will includearm_emit
&emit_core
(+HAVE_JIT
defined while compiling the whole code)Debug log
Here log file including JIT debug log
retroarch__2023_02_13__01_48_27.log
is there anything has to be changed to fix this issue?
Environment details
System: Windows ARM32
Platform: UWP
CPU: Qualcomm Snapdragon (8994)
it's pretty desperate situation when working on ARM32/UWP but any help will be appreciated as I'm looking forward to get DS emulation in better performance.
Side note
because of UWP security problem, memory cannot be protected as write+execute at once
as workaround (partially for testing) during the code I swap the protection,
I doubt I had issue with this because usually it will throw memory exception if anything went wrong.
but to confirm the only place I had to do this swap is
JittedFunc createFunc
atemit_core.cpp
Many thanks.
