@mitu geez that was quite a fast reply/clarification, no sooner had I walked away from my comp/posting then I realized I'd been remiss in not asking another even more pertinent question:
Have you all had any/many MicroSDs you were using on your Pis FAIL? (I'm guessing there are some informatively depressing threads here that can share some stories about as much...?).
At the end of the day, perhaps whatever larger MSD I get for these CDROM games (granted, I guess we'll see how many of them have stood the test of time to be worth keeping), ideally I may even have enough space on it to also fit what's on my current 128gb, who knows (and in turn, likely another 512gb/whatever to back THAT one up).
Ultimately, memory is never quite as pricy as the time spent collecting it...
