Haha I'm only looking to play a few games so I think 32gb might actually be perfect. Before I pull the trigger, which of these should I buy (or both?)?

Even if buying from SanDisk directly? Didn’t know there was much of a difference in SD cards but I found out it’s good to have smaller ones than one large one in case of failure etc

I had an issue with that card too. I have no idea why. But I tried 2 other cards (an 8gb SD sandisk and an 8gb pny mini sd with converter) and both worked fine using the windows formatting.

Also, it only took up 4gb to copy over every NTSC game in the N64 library. So 8gb is plenty. I have V3 so I also copied some NES games with no problem.

This is the one I couldn't get to work. https://www.amazon.com/gp/product/B0143RT8OY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
