M.A.D., or: Maeda Advanced Design Inc. in Japan, announced they will release a cartridge device which emulates the SC-3000 on MSX machines.
The SC-3000 is an 8-bit home computer produced by SEGA Enterprises Ltd. (current SEGA Games Co.Ltd.).
It has similar architecture to MSX, using the Z80 and the TMS9918A VDP.
M.A.D.'s cartridge, the MPC-EX256, abridges the differences from MSX, because it provides the required, among more, the SN76489 sound chip and I/O ports. Meaning, you can execute software of SC-3000 after patching it to change I/O port number to VDP.
A demonstration video that shows SEGA BASIC running on 1chipMSX is provided. Mr. Maeda, the developer of MPC-EX256 also says games for SC-3000 are available in the same way. He seems to welcome any contact from overseas.
