I m glad I?ve fixed this bug and I think it's time to close the topic

dink:
How did you fix it?

asdone7:
hello ，dink
           I modified a piece of source code, ?if (defined(__ARM_NEON__) || defined(__ARM_NEON)) && \ ? to ? if defined(PNG_ARM_NEON) && (defined(__ARM_NEON__) || defined(__ARM_NEON)) && \?

           In addition, I would like to ask you something about libretrofbneo. I want to turn off CRC check by default. What should I do? Can I modify the source code to do that? Looking forward to your reply. Thank you

If you need to run games with non-matching crcs in the libretro port, the supported method is explained there : https://github.com/libretro/FBNeo/tree/master/src/burner/libretro#i-patched-game-xxx-and-cant-run-it-why-
