The VRC7 mapper in the Famicom game Lagrange Point also contains a YM2413 derivative. Place the YM2413
: Some hardware-level tools, such as the Everdrive N8 , allow switching between different instrument ROMs (like VRC7 vs. YM2413) to change the sound profile of the FM output. such as the Everdrive N8
You need the ROM file that contains the instrument definition.
