Mariones 1.5 (2024)

The "Burn this one" directive was taken literally. The only surviving copy was a EPROM chip kept in a tester’s personal stash. In 2001, that chip was dumped and uploaded to a private FTP server. Let’s address the elephant in the room. Nintendo has never acknowledged the existence of MarioNES 1.5 . Forensic analysis by the Super Mario Bros. Disassembly Project (SMDB) in 2019 compared the hex code of the alleged 1.5 ROM to the original 1.0.

Whether it is a genuine lost prototype or the work of an assembly wizard with a sense of humor, MarioNES 1.5 has changed the conversation. It forces us to ask: What else is hiding in the developer’s trash bin of history? MarioNES 1.5
