Mahjong Lemon Angel (Japan)

Mahjong Lemon Angel is a tabletop mahjong game released in 1990 by Home Data, drawing its theme from the adult anime series "Lemon Angel." Players engage in two-player matches against computer opponents, choosing between betting point options of 10,000 or 30,000 per credit. The gameplay follows traditional mahjong rules, with a unique twist: winning hands unlocks animated strip sequences featuring the three main characters from the anime—Shima Erika, Emoto Miki, and Sakurai Tomo. Throughout the game, players accumulate "lemons" as rewards for successful hands. These lemons can be spent on in-game items designed to aid gameplay. Progressing through the game involves defeating opponents, with five consecutive wins advancing the player to face a new character and their associated strip sequences. The experience continues until all of the characters’ sequences are revealed or the player depletes their betting funds. The game's development was led by Fairy Dust, and it utilizes a Motorola M6809 and uPD7807 processor alongside SN76496 sound chip to deliver its visuals and audio on a horizontal screen with a resolution of 432 x 224 pixels.
