The VRC7 is an advanced MMC chip from Konami, supporting bank switching and IRQ counting equivalent to the VRC6, as well as containing a [[YM2413]] derivative providing 6 channels of 2-op [[Frequency modulation synthesis|FM synthesis]]. The advanced audio hardware is used only in the Famicom game ''Lagrange Point''. The Japanese version of ''Tiny Toon Adventures 2'' also uses the VRC7 but does not take advantage of the extended audio.<ref>{{Cite web |title=VRC7 - Nesdev wiki |url=https://www.nesdev.org/wiki/VRC7 |website=www.nesdev.org}}</ref><ref>{{Cite web|url=https://www.nesdev.org/wiki/VRC7_audio|title=VRC7 audio|website=NESdev Wiki}}</ref> A disadvantage of the extended audio portion is that it produces some quantization noise, noticeable at lower notes. This was a carryover from the YM2413, which the VRC7's FM chip is based on.
