reicast
reicast is a multiplatform Sega Dreamcast Emulator
To run the emulator you need to provide a copy of the dreamcast bios and flash.
In the internal memory, make a folder name dc, and a folder named data inside it, and put dc_boot.bin and dc_flash.bin in the data folder. You can dump these files from your Dreamcast (there are many tutorials on the internet).
If you use an android file manager, /sdcard/dc/data/ is the path to put the files
