Sometimes you see a video on YouTube and recognize you always wanted this solution in one package.
Please use https://github.com/danmons/retronas for installing RetroNAS on your device.
You can also download one of the following Virtual Machine to your computer, unpack it and import the VM:
Hyper V Windows 10 : https://mega.nz/file/zx4n3YbJ#ukqnFeA_E1gIibIGHvt0IUCHbCzInh912MYVWiefIEU
Hyper V Windows 11: https://mega.nz/file/29xjGYgS#MY8D02KIH2X97lj5bYSdzJ3szX3jAg1jMjNXSKErfMU
VMWare / Player 16.2: https://mega.nz/file/K5xVjCKZ#ecGI4oYi4FKKSIN4P4F0HZOznfAYZjaqeuaEKjdV6-k
Like Bob said be careful what you download from the internet. These images are meant to be unpacked and import in your HyperV or VMWare installation. They are made with the instructions of Dan with the same parameters except for the download mirror set to The Netherlands. They do not contain any extra software or roms.
If you want to create a RetroNAS virtual machine by yourself please consider:
1. In HyperV and VMWare disable Secure boot otherwise Debian will not be able to boot.
2. Networking has to be in bridge mode otherwise you cannot utilise all protocols.
