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-

Hello, when I read libretro.cpp source code, I saw [// addition to support loading of roms without crc check] function, can I modify the code to make it default support loading of roms without crc check

Sure, you can modify the code in any way you want. Just be aware that we won't provide any support if you are using dumps with wrong crcs aka bad dumps.
