Starting point:Traditional game simulators (FC, Neo, FBA, GBA, Mame, n64, NDS, and PSP) are all moved to Android phones, the game Rom is then saved to the SD card and run through the simulator. However, considering that mobile games must follow the fast forward and fast forward principles, I have implemented the following micro-innovations on this basis: 1. direc

Debugging related to SD card is often encountered in andorid development, such as MP3 files and image files. When developing a simulator, you can simulate an SD card through a hard disk. The specific method is: (1) Create an SD card
