(platfrom, miyoo) Core hangs before loading GUI menu - memory issue?

[Apaczer]

The scummvm core worked with old src (https://github.com/libretro-mirrors/scummvm), but here it just hangs before loading GUI and doesn't accept any inputs. There is also standalone version working from upstream as reference maybe?

DEBUG log just ends without any error on: [INFO] [Input]: Game Focus => OFF (retroarch.log)

I couldn't get this core to work after changes which brought current code inline with upstream. However I see that the core size grew from 21MB to almost double 35MB, which for a device who has 32MB RAM total (21MB free at best) is not best scenario. Any way to make output more stripped?

Can you test this build?

[Apaczer]

It's the same, but I ran custom core build (7MB large with only one engine) to see if I can get GUI running and got same result. My initial thoughts then might not be accurect. The DEFINES you have enabled indeed speed up scummvm loading in standalone version.

Ok then it should not be related to size or memory. Does it just freeze or also crashes? Is there any way to get system logs or crash logs on this platform? Have you tried to directly launch a game from retroarch to skip scummvm GUI?

You can also try to build your test version enabling the DEBUG flag to get a more detailed retroarch log.

The core just freeezes in the same place (at least reading from retroarch's logs), I need to send SIGKILL to shutdown frontend, no crash prior. Grabed short bt with DEBUG build, but not sure if it means anything:

Also impossible, same behavior when loading file.scummvm.

That's useful, can you test this build?

[Apaczer]

blimey, it does work! I was a bit confused at first because usual "left mouse click" switched from "A" button to "L1" and "A" is a quit event now. Thanks, feel free to close it when ready to merge.
