Have you taken a look at those videos? CEMU can't run most of those games, and probably will never be able to.
Really sounds like you haven't made one fucking second of research.
Let's go through the list, shall we?
Xenoblade Chronicles X : Already full playable on CEMU. Unplayable on Deaf
DK Tropical Freeze: Fully playable on CEMU. Unplayable on Decaf
One Piece Red: Much better performance on CEMU
Family Tennis SP: Crashes on decaf when loading a match, is playable on CEMU
Another World: Major graphics and performance issues on decaf. Not great on CEMU either but at least the graphics display correctly.
Nes Remix 2: Better performance on CEMU
Angry Birds Trilogy: Couldn't find anyone running that one on CEMU, but Angry Birds Star Wars runs at 60fps without issues. Angry Birds Star Wars barely boots on decaf
Scribblenauts Unlimited: Unplayable on Decaf as it bugs out on start, characters invisible. Can't find recent CEMU footage but back in the first versions it had visual glitches but at least it let you actually start playing it regardless
New Super Marios Bros U: Do I need to say anything? Much better on CEMU vs decaf, as usual.
Shovel Knight : Worked perfectly since early versions of CEMU, doesn't have sound on decaf.
Citizens of Earth: about even
The Cave: Shitty performance on CEMU. Crashes on the main menu on decaf
TNT Racers: Playable on CEMU. Crashes while trying to load a mode on decaf
Gunman Clive: Playable on CEMU. Extreme visual and audio glitches on decaf
Chariot: Playable fullspeed on CEMU. Can't play on decaf, green screen glitch.
Kirby Rainbow Curse: graphical glitches and needs a save game to get past certain points, but 60fps performance. Can't get past menu on decaf
Tekken Tag Tournament 2 : Extreme graphic glitches on Nvidia, better on AMD. Still quite a bit until playable without glitches, but you can get into fights just fine. Crashes after opening movie on decaf.
Like jesus fucking christ do your fucking homework. You're telling me to watch those videos when you seemingly have watched exactly zero of them?Holy crap.
We are not complaining about piracy, we are complaining about CEMU devs making profit from it.
Why don't you go on and fucking open a thread about how people who develop media players are extremely awful people because media players can be used for piracy? Why don't you go on and go on a dumb tirade against the devs of Drastic, a DS emulator on Android that is paid, and is also much better than the free open source emulators available on PC?
