Well, I actually have this one, but I'd be surprised if they aren't the exact same product sold by a different person...

I got a tiny adapter like this one. It's super compact and haven't had any problems with it. My small usb stick stick fits in perfectly fine, and I can charge with the same usb cord that the snes classic uses. Also works great on my Amazon Fire TV Stick and PS Classic.

This one is better.

I have tried three USB drives and three OTG, and have had no luck getting USB-HOST to work. I tried both FAT32 and NTFS. Both H2CE and Hakchi-gui methods.

I get the Hakchi loading screen, and my thumb drives light up, but I never see any of the games I loaded onto the USB drives, only the original 21.

Any ideas of where I could be going wrong? Or did I really get unlucky with all these devices?

For the record, I tried an "L" OTG and two Y-cable OTG's. The thumb drives were a no-name 4GB, a Kingston 8GB "DataTraveler Locker", and a PNY 64GB model P-FD64GATT4-GE.

These are good, as far as SanDisk, I recommend SanDisk for those, seems to have better results.

Followed ur video 2x too end to end and it doesn’t seem to recognize the usb at all. Using this adapter
