It’s a Japanese game compatible with the Japanese Master System or Mark III, which uses a different sized cartridge than the overseas SMS. The Japanese Sega SG-1000 used this same size cartridge, and the Japanese SMS/MKIII were backwards compatible with them.

The Samsung Gam-Boy (South Korean version of the Master System) also used the Japanese-style cartridges.

In Japan, they used the “Gold Cartridge” branding for first-party releases and “Silver Cartridge” for third-party releases.

ThinkPads still have real mouse buttons, at least. And some who copy the ThinkPad, like HP Zbook.

I still use my N900, basically just for ssh over wifi these days. It is so so so much better than typing on a virtual keyboard, especially in a terminal where I have keyboard shortcuts set up for home/end/pgup/pgdn/tab/etc. The original Nokia battery from 2009 is still live and kicking! The keyboard and slide form factor were great. Even the resistive touch screen, when used with the stylus, is very accurate.

The “Games” series was made by Epyx. First was Summer Games, followed by Summer Games 2, Winter Games, World Games, California Games, and California Games 2. They also released The Games: Summer Edition and The Games: Winter Excision. All of these games follow the same basic format.

California Games did have some more versions, Apple II, Apple IIGS, DOS, MSX, Atari ST etc.

Seconded this approach, I’ve got a Gentoo installation that has been going since 2005 across half a dozen different machines.

Was it The Journeyman Project?
