I want to write at this point not a full product evaluation, but give a specific reference for lovers of old video game consoles. I call a NES, SNES, N64 and Gamecube games besides handsome my own. The graph of the devices seen on the Grundig good, at this point I have nothing to complain about. But be careful: The television that appears in the image in response to input from the console has an enormous input lag is significantly delayed. (!). Say: plumber Mario is jumping overcome a canyon ... but it crashes always in selbige - because pressing too late due to the delayed image display.
So: a pure "staring" a decent box - for retro gamers but unsuitable. I'll see if I can get controlled by the Grundig support something else or find another solution. Otherwise, the device needs to adopt better or worse again.
