I select smash in the game menu and the screen goes black

Regarding Smash, I suspect you will need to increase your page file to 25000MB: https://www.thewindowsclub.com/increase-page-file-size-virtual-memory-windows
Regarding MK8, the game requires Mii services, so you need to dump your firmware. The process requires you to use Goldleaf: https://github.com/XorTroll/Goldleaf/releases

  1. Select Goldleaf from HB Menu

  2. Select console and Goldleaf settings

  3. Select Firmware and updates

  4. Select Export update

  5. Select Directory

  6. Wait for it to export

  7. Firmware ncas will be located in switch\Goldleaf\dump\update listed as the FW revision dumped
    https://cdn.discordapp.com/attachments/402241866935828490/727934352608198737/folder.PNG

Copy the contents of this dumped firmware folder to C:\Users\YOUR_USER\AppData\Roaming\yuzu\nand\system\Contents\registered

I was just pressing the button to go back ‘-’

but the game is very slow

Expected of an FX CPU. I really recommend you to upgrade.
