Regardless of framerate, limited controls, and other factors like that, is it possible, through some cfw exploit, cia application, to run minecraft on my old 3ds? This is purely for fun, i dont care if it runs well or barely at all. I know it wont work well. I know the controls wont work perfectly. Yes i have a new 3ds i can play it on, but i want to run it on my old 3ds just for fun.

Is this possible? Thanks!!

If you have a Old 3ds the answer was already provided by Zoogie. It crashes on title screen immediately. There isnt a way around this.

Probably because the n3DS has more RAM than the o3DS. n3DS "enhanced" games have to be able to run on the limited memory of the o3DS but n3DS exclusives can completely disregard the memory limits of the o3DS so as soon as the game tries to allocate more RAM than is available, it crashes.
Memory compression and/or a swapfile could be potential ways to allow the games to at least run, albeit even more slowly (memory compression is the best bet here for best performance but the 3DS doesn't have much power to run compression in the background and it might not compress the memory enough anyway, a swapfile would be extremely slow with the slow SD speeds on the 3DS, and you would have massive lag spikes, but depending on how often the game accesses certain parts of the memory, it might actually not be too bad), needless to say it would take in-depth modification of the system firmware to even make this a possibility, but it is a possibility, albeit a remote one.
It would be neat to see as a PoC just to be able to say "we got n3DS exclusives running on o3DS".

Ok, but still how would you use scripts in general, I have searched some forum posts and there isn't any results, like none of the things I see help, if you could let me know how to just use scripts that would be cool.
Thanks

I would be perfectly happy just getting to view the home menu and no gameplay.
This is more of a novelty thing for me.
Is there a way to run the game off my SD card with some application? I have luma CFW

Yeah just scan a qr code. Worked for me, it just doesn't let you load it
 
Can't it just boot to extended memory mode? I miss the legacy console minecraft before 1.19.84, minecoins, and all that.

Then what is the mode that certain games like Mario Maker or Pokémon USUM boot to?

Have a look at this:
https://www.3dbrew.org/wiki/Memory_layout#FCRAM_memory-regions_layout
Normal (most) 3DS games run in memory mode 0 giving 64MB of the total 128MB of the old models to the game. For some games this turned out to be insufficient (example: Pokemon Sun/Moon, Smash Bros). They use the option #3 with 80MB available (making the browser applet inaccessible during game and requiring a reboot for starting/quitting the game -- longer loading time until the game starts compared to games running in normal mode.
This third option is usually meant when talking about extended memory mode for the old models.

Looking at the last lines of that table, we can clearly see that the New type devices offer additional modes. New 3DS exclusives will probably use option #6. The old consoles simply do not have the RAM from hardware side.

I know this could potentially trigger some lame "download more ram" jokes. Please don't.

Honestly, this has always been one of my doubts. I always wanted to know what exactly would happen if someone tried to force the New 3DS exclusive on the Old 3DS.

I wanted to see if the game would run considerably slower, if it would crash after a while or if it would at least load into the menu. It would be interesting if someone took the risk of trying to do this just out of curiosity.

It reminds me of when you try to force a Game Boy Color game on the original Game Boy with a Gameshark like Pokemon Crystal for example.

The game boots and even a glitched version of the intro appears, but when the gameplay starts it crashes probably because of the RAM limit.

GBC games with DMG backwards compatibility map the four shades of grey used on regular GB games to four shades of some other colour. This allows GB systems to continue using four shades of grey for everything. GBC-exclusive titles are able to use different colours within the same sprite, which DMG systems can't understand.

As one example, look at the Skarmory sprite:

https://pokemondb.net/sprites/skarmory

Scroll down to Generation 2 at the bottom, and you can see how Gold and Silver use shades of grey, whereas Crystal uses purple and red at the same time.

N3DS has extra RAM and extra CPU cores compared to O3DS. As soon as a game tries to use a memorry address or CPU core that doesn't exist on the O3DS, the game will crash. It's unlikely you'd even get to the title screen, so the results would probably be even less impressive than trying to run Pokemon Crystal in DMG/SGB mode.

I share your dream friend, I also always wanted Minecraft for 3ds old. But complete, with the survival version, which to date has not been achieved, and with the release of Minecraft for New 3ds, I only truncate the projects for this console version.

You need a n3ds, you probably get like few fps on old 3ds.

yeah, but in the old 3ds it's more portable, the new3ds is very big and it's always been like that for me, maybe later on I'll decide to buy a used one just to try this game, since I've never even been able to try it.

You don't have to get the XL if you find XL to large for you, there is N3DS and N3DS XL.

The standard-sized N3DS is pretty much the same as the old standard-sized ones. I really liked the Ambassador Edition (bought it to resell it years ago).
