Abstract: A video game selection program runs on a home video game console system connected to the Internet and displays on a home color television set a menu of one or more video game titles corresponding to video game programs available via the Internet from a remote server. At least some video game programs available from the server are designed for execution by a computer having a different hardware architecture than the home video game console system. The video game selection program, in response to selection of a video game title on the menu, sends game title ID information to the server and downloads and stores both a video game program corresponding to a title selected from said menu and corresponding emulator program of a type especially suited for enabling execution of the selected video game program on the home video game console.

Abstract: A game system includes a first game machine which operates according to a first architecture and, a second game machine which operates according to a second architecture different from the first architecture and has a processing capability lower than that of the first game machine. A game information storage medium stores, in addition to a first game program executable on the first game machine, a second game program executable on the second game machine and an emulator program that converts the second architecture into the first architecture. When a predetermined condition is satisfied while a first game according to the first game program is being executed on the first game machine, it is possible to execute a second game according to the second game program using the emulator program.

Abstract: A game information storage medium is removably connected to a first game machine having a first architecture, and includes a game program for a second game machine having a second architecture, an emulator program for converting the second architecture into an architecture compatible with the first architecture, and a game selection program. When the game information storage medium is started-up on the first game machine, by executing the game selection program, the first game machine displays a game title to be selected by a player, and executes a game program of the selected game title by using the emulator program.

Abstract: A game program delivery system delivers a game program to a first game machine employing a first architecture. The hard disk included in a delivery apparatus stores a game program for a second game machine employing a second architecture, an emulator program and a game selection program. The delivery apparatus transmits the game selection program to the first game machine through the Internet to thereby execute the game selection program in the first game machine and allow a player to select a game title, and, when information representative of the selected game title is sent back from the first game machine, delivers the game program and for the selected game title and the emulator program. The first game machine thereafter executes the game program downloaded on a memory based on the emulator program.

Abstract: Various data required for a game as well as first collating music data are recorded on a CD-ROM (4). On the other hand, second collating music data and collating program data are stored in a ROM (302) in an external memory cartridge (3). A CPU (101a) executes collating program data at the time of starting a system, thereby to collate the first collating music data read out from the CD-ROM (4) and the second collating music data read out from the ROM (302) and allow the execution of a game program recorded on the CD-ROM (4) only when the data coincide with each other as a result of the collation.
