URCade

URCade can be installed on a Raspberry Pi or a x86_64 PC.
Here are the links to the files you will need.

Important: URCade comes with no warranty.
As previously mentioned, this is just a ready-to-use OS.
No ROMs are shipped, except the open-source BIOS that are installed by some emulators.
The system is under constant development, so it is not advised to install it on a "production" machine/device.
Always make a backup of your data prior to installing URCade.
Have a lot of fun using it! =)
