Non-MSX machines

blueMSX is shipped with different non-MSX machines; the required system roms are generally stored for each machine in a dedicated subdirectory of the directory Machines. The Sega SG-1000 console and the SC-3000 computer do not require a system rom to be fully emulated.

Coleco machines

Only the ColecoVision console is yet supported, this console has 4 non-expanded slots, 1 cartridge slot, 1 Kb Mirrored RAM and 16 Kb VRAM.

You can also use the Spectravideo SVI-603 Coleco game adapter or the ColecoVision with the Opcode Memory Extension (16 Kb RAM).

The video frequency is 60 Hz, but you can manually switch to 50 Hz in the Options/Emulation menu.

We hope to emulate in a future version the ColecoAdam computer that has more features.

Sega machines

Three Sega machines are emulated by blueMSX : the SG-1000 console, the SC-3000 and SF-7000 computers.

Sega Game-1000 and Sega Computer-3000 have 4 non-expanded slots, 1 cartridge slot, 2 Kb Mirrored RAM and 16 Kb VRAM. The SC-3000 can run games or applications that require a keyboard. The Sega BASIC comes on cartridges that have their own RAM (16 or 32 Kb).

SF-7000 is an extension for SC-3000, transforming it into a Super Control Station with 1 disk drive, 4 non-expanded slots, 1 cartridge slot, 64 Kb RAM and 16 Kb VRAM. A system disk is required to use the Sega Disk Basic.

The video frequency is 60 Hz, but you can manually switch to 50 Hz in the Options/Emulation menu.

We hope to emulate in a future version the Sega Master System with its advanced video mode.

Spectravideo machines

Five SVI machines are emulated by blueMSX. They have 4 non-expanded slots, 1 cartridge slot, 1 tape port, 16 Kb VRAM and a QWERTY keyboard.

The video frequency is 50 Hz, but you can manually switch to 60 Hz in the Options/Emulation menu.

Differences between these machines concern mainly the RAM, the addition of a drive and the presence of a second video card :

    RAM   Drive   Second video card
SVI-318   16 Kb   No   No
SVI-328   64 Kb   Yes   No
SVI-328 80 Column   160 Kb   Yes   Yes (for 80 columns)
SVI-328 80 Swedish   160 Kb   Yes   Yes (for 80 columns)
SVI-328 MK2   160 Kb   Yes   No
