When I first learned about Roms I heard Nintendo took down their games, but I wanted those Roms on my raspberry pi. So I purchased an SD card full of games. Going through it I noticed some games were in the wrong system category, for example Metal Gear for the PlayStation was in the Super Nintendo category. Am I able to simple put the SD card into my computer and click and drag it to the correct location or not? I'm still new to all this and still learning as I go. Any help would be appreciated. Thanks.
