Super Mario Bros. DX

Hack of Super Mario Bros.


First released on IRC and message boards in 1997, this graphical facelift project is celebrating 25 years! Super Mario Bros DX has evolved a lot since its early days of shading some background elements and porting sprites from Super Mario Bros 3, so come see what’s new! Check back occasionally, because there will be LOTS of fun extras added between now and 2024 (which will mark 25 years from the project’s landmark v1.0 release on Zophar’s Domain).

  • v4.2 UPDATE! This update includes a bug fix, a new title screen, and a historical archive of past versions–all the way back to 1997!

The aim of the project is to modernize the look of classic Super Mario Bros while remaining within the limits of the original programming and ROM size. There are no ASM hacks and no expanding the ROM–and no mapper! Just brand new pixel art (and a few things borrowed from later Mario games), palette edits, and metatile rearrangement. You can enjoy the original game with a fresh coat of paint, or try combining it with map or gameplay hacks that don’t change the graphics too much!

If you enjoy this project, consider saying hello on Mastodon:

Pretty frickin good.

Reviewed By: GlitchyTSP on 05 Apr 2019

This hack is perfect for anyone who wants to play the original SMB, there is so many way’s that this hack wins out to the original.

The graphics are even better than the original, my only complain is that there isn’t anything ‘new’ but it is still a really good time all-around.
