Mario's Game Gallery was re-released in 1998 as "Mario's FUNdamentals", presumably to appear more akin to previous Mario learning games. Stepping Stone had helped to develop this version with Charles Martinet recording some new minor dialogue.

Charles Martinet, the voice actor for Mario from 1990 to 2023, first officially voiced the character as part of a motion-capture Silicon Graphics interactive exhibition used at Nintendo trade shows (with the role at the time sometimes split between him and musician Steve Coyle). The first commercially-released product to feature his voice acting is purported to be the Super Mario Bros. pinball machine released in 1992 and produced by Gottlieb. According to Martinet when asked by a fan in 2018, Gottlieb "stole" his voice clips and did not credit or pay him for his acting. While the 1995 PC game Mario's Game Gallery is often cited as Martinet's first official role as Mario in a video game, the actual first credited video game to feature him as Mario is the 1994 PC educational title Mario Teaches Typing, where he replaced the DOS version's voice actor, Ronald B. Ruben.
