Technically true, but they are stupidly simple to make, and anyone can do it. Takes like one minute to bump the game's resolution to anything you want, you just edit a simple text file with some obvious values.
That said, Zelda HD remaster runs pretty bad on Cemu, so I don't have much hope for this either.
except they're not, they gave 7/10 for horizon! when you consider their notation system is in no way a bad score
for gamekult a 6/10 game is still a good game worth playing! People call them hater or blasé because they don't score game as high as other websites (for exemple, they never gave a game a 10/10, NEVER, that's just their vision), but once you read the full review, you know immediatly that they're very passionate, but tough
i don't always agree with them of course, but they're not hater regardless
