Mario Quest (Super Mario Bros. Late 1984 Prototype) [Mockup]

Mario Quest, localized in the United States as Mario's Adventure, is a prototype of Super Mario Bros. developed by Nintendo. This version of the game seems to take more inspiration from Mario's earlier titles (Donkey Kong, Mario Bros.). This ROM was found in October 2023 and seems to be from around December 1984.
The game feels much slower to play compared to the final game, and mechanics unique to this prototype such as screen-by-screen underground scrolling, auto-scrolling sky levels, and branching world paths were cut for seemingly no reason.
This is a mockup made by me, as I wanted to throw my hat in the ring for some "found media" fan content. I wanted to add more like a castle level and King Koopa fight, but I got burnt out on this and kind of just wanted to move on. Even things that were almost finished like a different version of the Starman and Warp Zones (called Negative Zones in this version) were cut. Maybe someday I'll work on a better - more polished - Mario fangame.

“Make it look like they’re playing Mario but just don’t make it too similar ya know?”

[@SonofMrPeanut]

This is what they'd be playing on Muppet Babies, given what their Donkey Kong looked like.

[@epiccoolguyLP]

similar to the mario movie where the donkey kong arcade game is just some other game instead of mario

[@SuperKlondike64]

I appreciate that there's no spooky analog horror nonsense, just a cool video.

Don’t really care for the analog horror twists anymore; one person did it then everyone started doing it & it’s stale now

Wow, what an incredible VHS tape. Really, I thought it was the best. I think I see a great future in you, making this type of content, and I'm sure you like making Mario Bros. ARGs. I see great talent in this. Great VHS. 👋🏻

[@Jayteaseepiirturi]

I like some of the visuals better here than in the final game.

[@scrubsandwich1050]

I love this! Can we get a version of this video without the applied Audio/Video Filters? Beta's of Mario Games have always been my favorite and one of SMB1 (even if fake) sufficiently peaks my interest! I also like the music, maybe even a rip of this OST? Perhaps I'm gushing a bit =)

[@mateuszszulecki5206]

[@JoeBee9]

I'm reminded of the Super Mario Land aesthetic; I love it :D

[@noone7400]

I was definitely expecting something creepy

[@ProGremlinPlayer]

I was expecting this to just be some analog horror slop but instead, it's just a really neat fan made mock up. It's like an alternate universe version of Mario 1. Pretty neat stuff. Hopefully more of this are made.

[@tomsvideosofrandomcrap6223]

The goombas came way later but other than that, very accurate

The fact that we don't have any of the SMB beta/prototype yet makes it seem legitimate and real to some extent. Pretty cool

[@cyberyogicowindler2448]

Now someone should implement "The Bishop of Battle".

this is a neat mockup but that first line in the description just makes no sense to me. why would a prototype be localized?

[@magoepico]

[@sgillman16]

Make it make sense. The arcade game Mario Bros. already existed, so they wouldn't call this "quest"

[@andrephillips2219]

i thought goombas didn’t exist until the last second of development though?

[@Xen0Heaven]

odd how no prototypes of SMB have ever been found,

[@benjaminreed5010]

Because there was no prototype. Scrapped ideas were never coded into the game.

[@champion_ofcloud-var]

@@benjaminreed5010 idea: thought up coded into game possibly scrapped at any time, even after coded into game like the tanooki leaf in mario world or the magenta block

[@jblassio]

Why are the graphics and sound so much better than what we got?

I'm the one that thnks that this is better than the final result? I know that's an hack, but is so cheerful with those sounds^^

[@AudioAndroid]

I'm going to need some more proof. I've never heard of this demo before.

[@windestruct]

I wonder why they decided to make the background scroll like on smb special in the underground level and make it scroll normally on the overworld level

[@DanielSong39]

Big improvement between the prototype and the final product Little things make a big difference! (We saw that again when Doki Doki Panic was refined to form Super Mario Bros. 2)

[@chimpmonumentis577]

While this is cool. I can’t help but feel like the fact that the game looks too complete does ruin the while prototype gag. I think for future mockups making the game have jank in the menus and some glitches would 100% boost that prototype work in progress fell. Mostly light glitches and debug menus and mem/cpu usages or something akin to sonic 1’s debug coordinates.
