The Analog NT is an FFPG NES "Clone" with modern updates like HDMI. This unofficial firmware update was released by the system firmware coder [kevtris] and offers ROM loading via the SD card. It supports over 200 mappers.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
