Bomberman GB, known in Japan as Bomberman GB 2 (ボンバーマンGB二 Bonbāman Jī Bī Ni?), is a Game Boy game released in 1995 by Hudson Soft in Japan and in 1998 by Nintendo for North American and European territories. It is the sequel to Wario Blast: Featuring Bomberman!. The game was part of a limited series of Game Boy games that were enhanced for play on the Super Nintendo through the Super Game Boy device. The enhanced game offered a special Bomberman frame around the TV screen, color graphics and custom explosion sounds, and a multiplayer mode which allowed for simultaneous gameplay between opponents up to four players through the use of a SNES Multitap. The game uses a password system to save progress instead of a battery back-up. Source: Wikipedia, "Bomberman GB 2", available under the CC-BY-SA License.
