MagicMemoryCreator requirements 'oschmod' and 'wmi' are not available on SteamOS/Manjaro/Arch

[sierra2600]

'MagicMemoryCreator' requirements 'oschmod' is not available on SteamOS/Manjaro/Arch, they're not available on 'pacman' nor 'yay'

'pip' tells me to use 'pacman' I've been able to find only 'psutil' and 'wmi'

I've added the Arch repo-name 'extras' to my 'pacman.conf' and they do not show in a 'pacman -Ss'

(yes... I've made sure to run 'pacman -Syy' and 'yay -Syy' )
