schematic is latest-greatest 4558CN should work fine C547B might not work fine, you may get slight distortion in FM HCT chips will work, each chip consists of 4 sections, refer to datasheet how to wire things... I'm not giving pin numbers since you have to make things yourself and how you place your chips might not be optimal for my pin numbers. difference is in that my method retains compatibility with MegaCD, 32X and Master System Converter, it works automatically so no user attenction is needed and there's a single switch disable function for some games such as Pier Solar and some chinese cartridges with copy-protection.
