It is even better than the US one. The US modell only has RF output which is horrible. This one has the typical AV port like the snes or n64.
The C64 can output composite video natively (with the yellow, red, white cables). You could buy or build yourself such a cable and then use an composite to hdmi converter box to use your modern monitor. Although I do not know if cheap ones will work with the signal, you have to do some more research on that.
I bet the throtteling is not caused by data scraping but by Twitter not paying their Google Cloud bills and therefore now with the new month they got services suspended.
I own a Virtual Boy. Not really super rare or anything but definitely obscure. Other than most people I love playing with it! Wish it had more games.
