Hello,
Due to my old PC can't use the "Hardware virtualization", so I can't use the Memu, then I found another emulator named "LD", I'm using the Simplified Chinese version (v3.58) and it's totally worked for FEH, no crash no 803-3001, you just need to download the emulator from their homepage and install FEH by apk, there are no any google apps need to disable because government of China ban google. Also I tried the lastest Blue Stacks but it's crashed.
If anyone the situation like me then you can try this. But one thing I need to remind that I have never use this emulator before, so I recommend that when you complete make the FEH account on this emulator, go to Nintendo homepage and change the password by PC browser will be safety.
