The positive responses to Pasta La Vista: Super Mario Bros. encouraged me to share another similar Super Mario World hack that released last year. Super Mario Bros. CD is a "what if" Rom Hack, what if the Nintendo Playstation released and had its own Super Mario Bros. game? Hack Info: Hack by: King Mayro, Famicom CD Team Patch version: 1.2 Release date: 10 October 2025 Source: https://famicomcd.org/smbcd

I wonder if this idea could lead to a new format, more NES-CD games, and an actual physical CD add-on similar to the Famicom Disk System. You, hardware geeks out there, get to work.

Just gave this a play and is really giving me the same vibes of the dynamic that Sonic 2 and CD had. Like if one team was developing Super Mario World in parallel to a different team developing this with this being more of a direct sequel to the 8bit Mario games while World advanced the formula into the 16bit era. Similar to how Sonic CD was more in line with 1 while 2 advanced the formula
 
Looks like turbo grafx cd game to me. Still cool.
 
Antipsychotics are usually prescribed, so I don't think they'd be illegal.
I meant drugs with a clearly OPPOSITE effect, not antipsychotics. It's more like something provoking depression.
Well, of course, since we are talking about Mario, the strange color mushrooms.

Yep. And 3D acceletor board fo ZX-spectrum. And CD addon too. Today we can implemented technically "in hardware" and create games thats use it. The question is, who needs it? :)
Anyway "CD sound" not it rom, they go separately and can be used only with some emulators. with functions that were not present in the central and in the NES audio processor, therefore, we are not talking about a supposed CD addon, but only about a stray to the emulator.
 
The SNES CD version from Nintendo and Sony is a real-life project but not released, and the NES CD is about fantasies under illegal substances.

Discs and disks aren't the same thing. And why are people here getting mad over nothing? Jesus, you're on a gaming forum, no one cares about your ego, and I'm saying this in a good way.
"don't get so mad bro, i'm not mad you're mad"

ur hecking epic dude, take my reddit gold
 
The Nintendo Playstation was a Super Nintendo CD add-on not a 32bit 3D system.

Afaik there hasn't been any updates since last year, but yes this is only a demo, five selectable levels and no boss fights.
On the FamicomCD website they state "The name relates both to the team, and the fictional Famicom add-on that our games are based on; it should not be confused with the unreleased Super NES CD-ROM/Super Famicom CD-ROM."

So saying that "Super Mario Bros. CD is a "what if" Rom Hack, what if the Nintendo Playstation released and had its own Super Mario Bros. game?" might have changed some peoples expectations.
 
Looks like a SNES Mario 1, not a PSX one, but it looks cool either way.

It is said a demo but....is this full game?

I get what you mean.
For the most part it feels like it uses music files that demand that extra space. It kind of feels like a waste of capacity to stop there; especially with how crunchy the sfx and music sound.
I would have expected a least the addition of large sprites to make it worthwhile.
Really CD size compared music extra space? An music in CD-DA format consists of two-channel signed 16-bit LPCM sampled at 44,100 Hz? Don't think so - SNES supports 16-bit audio, but has a limited sampling rate. This follows from the characteristics of the sound system: the DSP generates a 16-bit analog signal at a frequency of 32 kHz, mixing the signals received from eight independent oscillators and a filter. So don't get out of it - technically, the SNES is not capable of playing full-fledged CD audio. And of course the NES certainly can't. The fact that some MODERN emulators can add third-party music to games and substitute sprites does not change the situation.

There is some not standard .pcm sound with hack - lazy to find what player can open it to check audio quality. But in total, these files are less than 200 megabytes, not 600+, and there are some doubts about whether they are inflated?

I'm afraid, as I already hinted, large sprites are technically not feasible at all (hardware limit) or at least without a major redesign or complete replacement of the game engine. But this is still a romhack (we like romhacks here!). And there is a real 3dSen emulator that translates some NES games into 3D - but the NES and even the SNES couldn't pull this off.

Is anyone else having an issue with the music playing fine but the sound effects are muted?
I'm using the Retroarch SNES9x core as the source suggested, current version from the built-in core updater as of today (1.61)
It works as intended in standalone SNES9x.
It's likely an error on my part, but I thought it was worth asking.

By the time it became technically possible and economically feasible to release CD addons or full-fledged CD consoles, the 8-bit NES was no longer of interest to console developers, game developers, or the players themselves. Yes, we still love the NES and its games... but "If ifs and ans were pots and pans"

When Nintendo tried to cooperate with Sony, the initial idea was to release a CD addon to the SNES (not NES) and possibly a next-generation console with CD media instead of cartridges.

And when they couldn't come to an agreement (because of Nintendo, by the way), Sony took a chance and released their console Playstation. And they didn't lose.
During the same time period, there was many talks of the next Mario game, which the development team DEFINITELY REPEATEDLY stated would be 3D rather than 2D. So the NES is not at the checkout here anyway.

My main thought is:
By that time, everyone had already forgotten about the NES a long time ago at moment we talking about. That's why I wrote that the hack looks lackluster for such an unreleased console. Unfortunately, hack looks graphically weak even compared to later NES games although it is made on the SNES engine of the game, because of the chosen color solutions and perhaps the "talents" of the author, it looks not even like the SNES, but like the NES, which is what I WROTE ABOUT.

Moreover, there is NOTHING that could require a CD addon in this hack, even in a very remote approximation. You can't jump over your head without special tools that neither the NES nor the SNES had. In early console CD games, the media was mainly used for high-quality music, video installations, large sprites and animations - are we seeing any of this in this hack? Not at all.

thanks for repeating my post as if i didn't say exactly that::huhsonic

It's only because CD's did not exist, otherwise it would've been a cd add on.

furthermore, if people wanna make a comparison they should've taken the SNES.
The Famicom Disk System came out in February of '86.
NEC released a CD add-on for the PCEngine in December of '88.
The Super Famicom was still two years away releasing in November of '90.
The technology was already there, so you could image Nintendo competing with NEC and maybe even getting a CD add-on for the Famicom to market first.
This would give this game a pretty good two year window to exist. Especially after '89 most releases moved away from the FDS anyways.
 
This hack is a "what if" the NES/Famicom had a CD add-on. It uses the underutilized SNES video MODE 0, limiting sprites to 4 colors, like the NES. In return, it offers 4 background layers, which the imaginary FamicomCD add-on would have provided. This has nothing to do with Nintendo's PlayStation.

Great concept! This definitely would have been a great game for sure!!

It had a disk addon.
