Quick Review
This is an awful device, software wise. You cannot access saves/states, you cannot add/remove BIOS, you can’t do a lot of things. The OS is written to the internal storage, not an SD card – there’s no way, with Windows, to access those files. The SD card part is for roms only, nothing else. I’ve been told you may need to spin up a Linux VM to be able to access the internal storage, or you can buy and use a WiFi adapter to try FTP (which I don’t believe it even has?) or you can go on a system by system basis to change where each core is looking for saves/states/bios.
Or you could just not buy this thing since it’s not doing anything special.
Do not buy recommendation.
