Remarked ICs can usually have their surface scrubbed away using acetone and a cotton swab. This should not happen on a non-remarked chip. Remarked chips also have a unique "rubbery" feel to the surface if you rub your finger along it - hard to convey via text, but obvious if you have a few examples of good and fake chips. Keep in mind, however, that just because the chip was remarked, does not mean it's not a real YM2612!

# Look at what you receive

In every single case of fake chips I have received personally, the photos on the seller's listing were of legit chips. Inspect the chips you receive, rather than the promo photos.

# Testing fakes in-circuit
|
|
|
Testing fake chips in-circuit is not recommended. The incorrect package style is enough proof that the chip is fake. Some of the fakes have been confirmed to be 6116 SRAMs and the pinout of these chips could result in damage to the host device if inserted where a YM2612 should go.

# Getting a refund
|
|
|
Sellers of fakes may put up a fight when you ask for a refund. I would stick to something along the lines of "the chips are fake and do not work". Keep it simple and stand your ground. Don't be afraid to get PayPal or your credit card involved if the seller won't give you your money back.
