Downloading the game on Nibble

Hi guys! Here in the society there is a homemade shooter for Nibble. I tried to upload it to the console for an experiment, but nothing happened. Can you tell me how to upload a game file to Nubble? I connect Nubble via a USB cable to a PC, but the system does not see it as a disk. I.e., it does not work to copy the game file to it as to a USB flash drive. How do I install the game on the console? Thanks.

I found the topic “Can’t upload to Nibble”. I will try to do the actions using the Circuitmess software.
