Im not sure why i want to do this by i find it annoying to have to reinstall a game with every new computer and console ive gotten over time. How would one make a offline installer or backup, I would also want to make them look like retro media if possible.
By chance are there better ways of re installing games without torrents?
Due to how they are affected by Bit Rot, I would bot use any kind of flash based media (USB Flash Drive, SSD, MicroSD, etc) for any kind of long-term backup.
