The mobo is the same, the ROM board is different. The compatibility of the multi will depend on if they create a whole new ROM board, which he’s indicated he will in the first post.I am not sure that GunForce will be compatible with this multiM92. Its mobo M92 is different as the other M92
All ROM boards use PLLC 08J27291A1/8J27291A4/8J27291A7/8J27291A8 etc.. parts. These are sound CPUs. Do they differ each other? Are these some official parts or a geniue ones?
Earlier ROM boards uses GA23 parts while never ones use 08J27504A1 and PD65082. What do these chips do?
