Google Chromecast with USB C Hub - Google TV #shorts

Where van i buy this

Mine will read but wont write to external storage. I am using ugreen hub, with 25w PD, and File Manager.

Fat32 only.

I even have a sd card in my hub an installed john NES nintendo entertainment system emulator and added a filder containing about 50 old NES ROMS and paired an xbox one Bluetooth controller and chrimecast can now be used as an old school NES console. Only problem is the john NES app doesn't show up on my Chromecast homepage i have to go into its settings go to apps select the emulator and open it from there. Anybody know why it cant be added to Chromecast homebar? Its not because its a sideload apk because all of my illegal movie and show streaming apps inhave and use all show up on my homescreen

I knew it can, but I can't find a hub in the Netherlands/Holland that will work with the chromecast.
I heard also that you need another power supply, because the power supply that comes with the chromecast don't have enough power for a harddisk.

I've tried different c type hubs..wasn't successful
