Usage


MESS emulates the following computers

* sc3000 [Sega SC-3000]
* sc3000h [Sega SC-3000H]

For both, MESS requires a cart dump (in .sg, .sc or .bin format) in the ''cartridge'' (''cart'') device. You can launch emulation using, at command line

mess sc3000 -cart "C:\pathtogame\gamename.sc"

Also, MESS supports the emulation of the sc3000 and sc3000h with a ''cassette'' (''cass'') device, for tapes in .wav format.

Finally, the ''printer'' (''prin'') is emulated.

Notice that MESS also supports the floppy disk drive, see the sf7000 system (i.e. the Super Control Station, which consists of a SC-3000 with the SF-7000 floppy drive).

Starting the Machine

As mentioned above, you have to start sc3000 emulation with a cartridge image inserted. This system has no built-in OS or Programming Language, hence you need at least the BASIC cart to load tapes or write your own programs.

Keyboard

These systems require full keyboard emulation to work correctly. At startup, full keyboard emulation mode is enabled by default. Whilst in full keyboard emulation mode, some key associated functionality may be disabled (like the ESC key for EXIT). The keyboard emulation mode is toggled using the ScrLock key (by default). The keyboard has the following layout:


1! 2" 3# 4$ 5% 6& 7' 8( 9) 0 -= ^~ ¥| BREAK Power RESET

Controls

The computer features a "Reset" button on the keyboard.

In addition to keyboard, you can connect a couple of 8-way joysticks, with two action buttons each, to control SC-3000 games. The game "TV Oekaki" allows to use a tablet to draw pictures which are displayed on the screen.

History and Trivia


The SC-3000 is a computer based on the hardware of the first video game systems released by Sega in Japan: the SG-1000 series. It can use the same game cartridges marketed for these consoles.

The SC-3000 can't be used without a ROM cartridge, which can be either a game or language. There were three different BASIC cartridges. One came with only 1Kb of RAM (and you had only 512 bytes free!), the second with 16Kb and the last with 32Kb. In official adverts, they show a total RAM of 48Kb. This was counting the VRAM and the 32Kb BASIC cartridge...

Several great games were adapted by Sega for this computer. Several graphic characteristics of the SC-3000 are fairly close to MSX ones. For example, it was one of the first computers to offer 32 sprites.

Some months later, Sega released the SC-3000H which was the same system but with a mechanical keyboard.

This computer was also marketed by Yeno under the same name (Yeno SC-3000 & SC-3000H). It was exactly the same computer except for the Yeno brand...
