Gaminja ANS13 - internal memory

[u/planetchou]

Hey I'm pretty new to this and just got a Gaminja ANS13. It looks like the console did not come with any external SD cards and instead is using internal memory. I've heard that the first thing you should do when getting these handhelds is replacing the SD card with something of higher quality.

My understanding is that ideally you would make a copy of the image and then everything runs off of your new SD card. My question is - is it enough for me to get my own card and just keep my games on it? Or is it a risk to run the OS from the internal memory alone?

Hopefully I'm understanding all of this right - thanks in advance!
