Note: I’ve recently learned that there have been updated versions of this homebrew released with graphical and control fixes, along with improved features closer to the Game Boy original Super Mario Land. This review and gameplay video has been updated to reflect the version 1.2 of New Super Mario Land as of 2/26/2020.
So I came across this little homebrew completely by accident, a SNES homebrew version of the Gameboy classic Super Mario Land. I had never played SML before or had a giant brick Gameboy save for playing emulators back in the day or borrowing a friend’s (I think that’s how i finished the og Link’s Awakening and Pokemon Red). Finding the rom, I fired it up on my phone emulator and had a blast with it! This project was originally a homebrew of SML as a Christmas gift for the anonymous programmer’s friends. Of course this being 2019 the rom got dumped online and can easily be flashed to a cart, or played on your favorite SNES emulator. I recommend Snes9x or Bsnes.
You can find more information about this amazing project and its history and videos at the below articles. For security purposes I won’t be providing a direct link to it, but you may find it on archive.org.
