In the past, Yamaha released two soundmodules for the Yamaha CX5M MSX computers. To use these expansions on other MSX computers, a special adapter is needed. Both expansions were quite ahead of their time. The software of the SFG-01 was only capable of saving to cassette, while the software of the SFG-05 could save to disk as well. Richard Atkinson has succeeded in updrading the ROM of an SFG-01 module to an SFG-05. Because both ROMS differ in size, some modifications had to be made. Address line A14 from the cartridge connector is soldered to A14 on the EPROM.
