The logo and text are completely wrong, and the date code is nonsense, which is evidence of remarking. The chip has two ejector pin markings and a notch, but does not match any known Yamaha YM2612 package styles. The key point to notice here is that the notch is shallow, and does not go all the way through the chip. It's not even worth testing these chips in-circuit. **Fake.** Aidan Lawrence has identified many of these fake chips as actually being 6116 SRAMs.

# 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.
