In the electronics community in general, a chip that has been remarked in any way would be considered fake. For the purposes of this document, "fake" means a chip that does not work, specifically because it is not a YM2612, but has been remarked to look like one. Remarking is a common practice among sellers of obsolete ICs and is nearly unavoidable when sourcing YM2612s, but recently sellers are starting to send out completely fake chips.
**This page contains the following:**
