I am more interested in second generation of games that included the FM sound track. Japanese cartridges should have a tendency for different sizes ...
If it is possible to recycle old pads and controllers, why not music chips?
msx music chip or the 2413 ? I was under the impression they aren't the same thing, in that the msx music chip contains the 2413 and can access a sample ram?
boblet, no, you're totally confused here. There exists an FM-PAC cart which has an YM2413 and an FM-basic ROM (together MSX-MUSIC), and an additional SRAM in which you can save games.
