While reading Satoshi Matrix's blog (http://satoshimatrix.wordpress.com/2010/01/06/dream-castlevania/), I stumbled across Dream Mary for the first time. For those who don't know, it is a cartridge mod that interferes with the game's mirroring function creating a "a bizarre scrolling effect in which the screen splits in half: the right half is unchanged but the left half of the screen displays what’s way ahead of you, on the next screen" (http://133fsb.wordpress.com/2009/11/21/dream-mary-on-a-budget/). I wanted to know what if anything noteworthy ya'll might be able to tell me about the lore of this interesting game modding technique. Any and all links are also appreciated. Thanks!

This was discovered on Famicom World. There's a chinese famicom pirate of SMB1 that's incorrectly wired called "Dream Mary". The result was a copy of SMB that would scroll incorrectly, showing what's about to appear before it does.

You can do this with any mapper 0 game. That means early NES games that use either the NROM-256 or UNROM boards. Those early games literally have points on the pcbs that control the scrolling. Later, more advanced games used memory mappers (MMCs) that took over this function. I have three games that I've done this simple hardware hack to.

If you'd like, i can post a video showing them.

I would like to see this, if it isn't a hassle.

I would like. :)

I've already seen your Castlevania one, but you might as well post it for the benefit of those who haven't seen it.

It isn't a hack in software, but rather in hardware. The physical mirroring points are reversed and this is the result.

It isn't broken as all that's changed is the virtual and horizontal mirroring. What you're missing is just that its a cool novelty one can do with UNROM and NROM-256 NES games.

Who said that? I wasn't even the one to start this topic! lol Again the "Dream" series is only for novelty sake.

Because its novel, its interesting, and adds challenge to games you can otherwise breeze though.

The second url in post 1.

"Dream Mary is quite a unique experience and as such is often sought among Famicom collectors."

I'm puzzled why anyone would want this. The appeal is certainly lost on me. It's just a game that isn't working right.

It is the idea of chaos breaking into the ordered world of the video game that appeals to me, I suppose. By performing the Dream Mary hack, you tear a rift in the Super Mario Bros. universe. While this rift won't flip the Mushroom Kingdom on its head to where hammer head brothers sit around and recite beat poetry rather than throwing hammers, it is still novel enough for me to say, "what the hell" and buy an extra Mario/Duck Hunt and mod it. On a final note: I have fond memories of playing video games that "decided" to glitch out on me, bashing numbers and strange shapes across the screen. It was always a strange, interesting, and slightly disconcerting experience that I welcomed.

As far as modding the Mario Universe, check out this video (http://www.coryarcangel.com/things-i-made/supermariomovie/) of Mario's universe deteriorating. It is a collaboration by Paper Rad and Corey Arcangel, and here is a poster for the movie.

There's a great many videos on Youtube of SMB being corrupted in many random ways. See for instance http://www.youtube.com/watch?v=0bgomwomhJ4 .


It isn't a hack in software, but rather in hardware.What I don't get is that the link in the OP says it can be found on multicarts. I guess that means it can be done in software after all, if one really wants to.

It can be done in software if you deliberately change the values of the scrolling, but that's most likely not what the chinese pirates did. Rather, they would have screwed up the mirroring traces which would affect ALL games on the multicart, but you simply don't notice because the majority of early Famicom games are fixed screen games that don't feature scrolling at all. For those games, screwed up mirroring in the scrolling doesn't mean a hill of beans.

I have something new, inconsequential as it might be, to add to the thread. Evidently there are at least two different types of pcbs inside of Mario/Duck Hunt carts. From the three I have opened, the two with flat-head screws had pcbs that had the H & V mirroring select solder pads, but the cart with the 3.8 security screws did not have them, rendering them unmoddable (at least by me). The other difference is that the connector pins at the bottom of the unmoddable pcb have a gap in them while the moddable one's pins have no such gap. Without question, this discovery will usher in a new paradigm shift in retro gaming. You saw it here first, gang. ;)

Here are front and back photos of the pcb that is moddable:

Indeed. the globtops conceal the traces, making a SMB/DH cart produced after 1988 impossible to mod for Dream Mary. The best best for finding a cart you can modify in the "Dream" fashion is five screw games.

I have nine copies of SMB/DH (I got them for free from a game store that was going out of business) and only one of them is the 1987 version with actual mask roms.
