Even though the game does have its haters, known romhacker infidelity has taken upon the task of porting the entirety of Zelda II into the SNES, which he did a couple of weeks ago back in June 28th, 2024. The port itself features some slight quality of life changes over the original, offering less slowdown, less flickering and, until just a few minutes ago, infidelity has been able to implement full MSU-1 support into this new SNES port, which means CD quality music playback for the game.
While some might see this as just mute work and unnecessary, it is nothing short of a technical wonder, showcasing the capabilities of the modern day when it comes to romhacks altogether, and that given the proper knowledge, entire ports into newer consoles can be made, and with even bugfixes or more features than the original.
