2. Write the Image to your SD Card
Finally you need to write the software in the SD, you can download Win32DiskImager if you are on Windows. Etcher is recommended if you are on Mac or Linux.
Open the program and search/select the RetroFW.img image file. Select the drive letter for your SD card and press Write.
After the write is complete, your OS may prompt you to format the card. This is because it does not recognize the data on the card. Just click "Cancel" and remove the card from your SD Card reader.
3. Finish Setup
Plug the SD card into your console's internal SD reader. The first boot will attempt to expand the filesystem to use all the space on the card. This may take a few minutes. The expanded size will be shown on the next and your system will be ready to use.
