This hack is strange... for all the right reasons

Reviewed By: hdofu on 15 Aug 2021

It needs to be stated that Strange Mario Bros is rom hack from another era at 22 years old. That’s one of the reasons it is strange is that it actually is a quality hack with a good level design that is actually fairly balanced on par with the original game. Anyone who was around looking at rom hacks back in 99 will remember it was an era of file-sharing hosts trying to bundle every ROM hack under the sun they could score their hands-on per game and anyone who has scanned one of those bundles will know that this was not normal of rom hacks back then, yes there were stranger hacks (usually extremely racist) but most of them were barely playable and in some cases completely unplayable with more accurate emulators.

Another strange thing about Strange Mario Bros is when in a Zip filled with 100 of ROMs it still manages to stand out and set itself apart. Compared to the original game it’s strange, but compared to some other hacks its strangeness is much less about sprite redesign and more about using things in game in unexpected ways.

It definitely is a product of a different time, but in many ways it makes it feel closer to Super Mario Bros, its different enough it isn’t just a level hack, but it isn’t so different that it feels uncomfortable to play as a SMB vetran. In the days of drugs, nudity, racism and other various forms of graffiti hacks, Strange Mario Bros was strange for being a quality hack when putting an expletive in the tiles or putting Mario in a Wheel Chair was considered a rom hack.
