Even the big Neo-Geo ROMs?
If you don't have any issues, I'll probably do with a "middle" range one with like 60X or something instead of the 133X or whatever that some people suggest.
I actually had a very similar situation.
I ended up returning the SD card to the seller (still waiting for the refund).
I browsed through his ratings a bit more and noticed some people had Sandisk verify that his cards were actually counterfeit. I thought I was buying a nice Sandisk card, but...
I'm wondering if I should get a regular SD card or pay an extra $30ish more for the high speed version
I guess my main concern for speed would be video playback and the larger Neo-Geo ROMs that need to stream.
Does the extra speed make a difference in smoothness of playback and emulation?
