The old fashioned standard dimensional games are a matter of past now. The new versions of most of the video games are coming in greater visual effects and three dimensions. Even then, if you are fond of some old games like Super Mario or Sonic etc. you can even play them in way better than their native 720 pixels resolution. Thanks to the new Wii U emulator which can emphasize the visual effects of anything on your screen multiple times. The visual effects are not just doubled, they are quadrupled which gives you an unexpected experience of your gaming fun.
The Wii U emulator Cemu has a capability of playing ordinary video games as much as it has of playing the console games. The emulator plays the console games in a resolution of 3840 x 2160 which is even higher if you multiply the ordinary 720 pixels. The latest version of emulator is Cemu 1.70 that allows you to play a variety of Wii U games. By including the Bayonetta 2 and Xenoblade Chronicles, the emulator gives the highest resolution in a variety of games which you can test. I have experienced almost every game which I could think to test this and found it pretty much better than I thought it will be.
The resolution that you want is in your approach but you have to patch the game code to get that. The emulator works by integrating the specific game patch codes which you have to hack yourself. This requires a bit of your effort, but surely it is worth. The comparison of Cemu 1.70 with any of the old version or other classes can amaze you. Likewise, the comparison of Cemu with the Dolphin emulator shows Cemu gives more than double of everything. It ensures such kind of results by doing a lot of unconventional things.
