I have an rpi4 with retropie running, and was able to play for several hours with no issues.
I started with a base raspian image, and followed these instructions here to install retropie:

@namrood The technicalities will vary from country to country. IANAL but I would say infringement of intellectual property rights and the distribution or downloading of any software containing copyrighted material which you have not purchased through the appropriate channels is probably illegal. I've no wish to get into a legal discussion. My original point stands and it is stated within the rules of the forum. Third party images are not supported.
