Hardware Eevitronics' EeviCart Pico - new DSpico board with built-in SD NAND

[Tofu_mommy]

Can't wait for someone to mangle this idea into a new way to make fake game copies to scam people. Nothing against the project, I just immediately see the worst possible use by bad actors. They will no longer need to solder down a microsd card.

What are you concerned about? There are already repro carts being sold online (check aliexpress)

Pokemon games are already a no-go, they're 512MB ROMs and won't fit in the 256MB of space, even trimmed. So essentially useless for like 90% of DS owners. I'd rather see a DS clone of the DSPico with an SD slot and USB C port. But the SD slot on the side, not the top. I don't need to accidentally spring-fling that bitch out in front of me somewhere.

There's an 8Gb version, the games will fit:

They already didn't have to anyway. This isn't a new thing, the old DS Fire Card was dirt cheap and commonly used to make bootleg multicarts because of the onboard storage. People AFAIK never tried to pass them off as legitimate games because DS games weren't expensive and it was probably more profitable to advertise 200 games and charge suckers like 50 bucks for it (even if they were trash games because it was the way to maximize the number, and there wasn't even any room left for save data in some cases)

Hey! I am the owner of Eevitronics and the designer of the EeviCart Pico. I am very surprised to see my site here.
Thank you for your email SylverReZ, i am happy to answer any questions here.

I was reading everyones messages here and i am sorry if the price is a little too high, i am just kind of feeling out the market to get an idea. I only did a small batch of these to get a feel for the market.

I designed these as i am wanting to sell them in a larger lot to Homebrew developers who would like to have a complete package. I have sourced some labels, shells, boxes etc.
If you are a homebrew developer and wanted say 100 cartridges, then i can supply you a finished product, or even sell them on Eevitronics.
I have sold quite a few this weekend and the next batch should be a little cheaper. What do you think would be a reasonable price that would make you buy them?

Thanks again for posting this SylverReZ and for all your feedback and comments!

@j4m13c0 thanks for the response here!
I understand that that it's not the intended use, but can we flash a real rom (backup of course) to this, any compatibility issues that could arise? Am I thinking it's too simple?

I like the GB/GBA simple flashcarts that you can flash yourself, and interested if I can do the same thing with this cart too.

Yeah, you can do. Its compatible with all the same ROMs that the DSPico can use. The firmware is pretty much identical. You can even flash the stock Firmware onto it, if you really wanted to. (Cut a USB Cable in half and put a 5V to 3.3V converter in the middle).

I will be bringing out a USB Cart Reader that will allow you to interact with these as well as the stock DSPico in the future. At the moment you can "flash" them by copying the Homebrew ROM of your choice to the SD NAND storage via GM9i.

If this is made for physical release homebrew the minimum storage size is a bit big IMO, most homebrew doesn't take up that much space.

Releases like Bilou School Rush or Cave Story are maybe a few megabytes. Big source ports like Classicube, XTech, and CQuake take up more space since they need textures and stuff but 256MB is pretty overkill for any actual homebrew releases

EDIT: 512MBit is 64MB that's a really reasonable size for most software

You should be able to fit a small handful of games onto one of those, best to trim them if there's plenty of empty space at the end, but I don't know how this would affect Pico-Loader. Otherwise, I don't think it's that bad as people seem it is.

Note that the site is listing the capacity options in gigabits. 8gbit == 1GB (gigabytes).

Yes, the user I was replying to likely didn't understand that.

I used "Gb", that exact capitalization refers to "gigabit".

 

[Apache Thunder]

Oh I see. I thought you were referring to that as 8GB in that post lol. The whole gigabit/gigabyte stuff has always been confusing. Fun fact, most N-Cards use megabits/gigabits to describe their capacity as well but there was one very specific branded one that for some reason labels their capacity in gigabytes instead. DS-Linkers, ExpressCard, DS Fire Card, etc used the megabit/gigabit convention, but N-Card branded cards used gigabytes. I call them N-Card clones but technically they are all just rebranded DSFlash2 carts as I believe that was the actual original vender/brand name the hardware originated as. But I suppose I'm still used to calling them all N-Cards because I owned an N-Card branded one back in 2008 or so so now that's what I associate them as.

Anyways 1GB of space is enough for a few games if you make sure to trim them. I have 6 DS games and 6 DSiWare/DSi Enhanced games set aside for it and it's only 694MB (and that includes Pokemon Black 2 which trims to only 287MB. They just barely couldn't fit it on a 256MB cart. ). That includes the few bits of homebrew and such. So it's enough in some cases. Maybe not for multimedia like Moonshell2/FastVideoDS stuff. You'll eat up that space quickly with that.
