Best microSD Cards for Retro Handhelds

What to look for

• ✓ A1 or A2 app class — The Application Performance Class guarantees the random IOPS that keep emulators and game menus snappy.
• ✓ Reliability over huge size — ROM libraries are small next to modern games — a trustworthy mid-size card usually beats a giant bargain-bin one.
• ✓ Good price per gigabyte — You rarely need a top-tier card here, so value is the deciding factor — we sort by $/GB.
