history lesson? they still make those or more precise, there is still alot of them still available.

With all the flashcarts of any make and model that can only do loaderless, you had to manually manage your saves or kiss any amount of time you put into the save good bye.

As to if this is the case with the Crown3DS, don't know, don't care, and they didn't say if that was the case or not.

I remember seeing similar carts for the genesis back then. I think even the n64 had something like this to load a single rom to the system

Alot of you on this forum are probably too young to remember these. This is a 64 megabit gameboy color flashcart along with a xchanger. These cost about $175(1998ish dollars) or so if my memory serves correctly. The cart looked JUST like a gbc cart as far as the gbc could tell. There was no external storage, just 64 megabits

You talk like it was years ago. These were very popular even 10 years ago.
You contradict yourself here, first implying it was not years ago, then going on to say it was. "years" is simply more than 1 year, so 10 years classifies.

For holding only one ROM at a time, 64 megabits (8MB) sounds like a lot. Why not just 1MB? Were there even any GB games that hit 8 megabits/1 megabyte?

for 99Euro they can make an LCD Screen on the back of the cart, like for Drive emulators like WODE etc., so that we can choose at least the ROMS.

Ya know, I'd be happy for it to be 50 quid.

edit: crown3ds team are ignoring all my emails. they must be gone. oh well.

Il be happy if its 50$. Thats 10$ more then a single game. I just cant afford most of the games, along with all the console games i buy (and then a PSV)....god it sucks to be poor and in college...

i tried "tweeting" them but that goes unheard. Il try and email also, though i have a feeling they just can't get something to work so they cant actually release anything.

Miniturizing a test board takes time unless you have done this before. When I worked on prototype boards, miniturizing took a few months IF your doing all the work without prototyping software.

Otherwise, pestering them via any communication method will not make things go any faster.
Yes I am sure they have never done this before and aren't using prototyping software

Considering they managed this, which no one else has publicly done, I'd say its a safe bet they know what they are doing, and probably have a large enough budget to use prototyping software.

yea i suppose they could ,but that would be really goofy looking and yo would have the screen sticking out ,or if detachable you would hav to carry that around
i think the best option as someone else said would be to have an onscreen menu to select the roms from ds mode, you could use ds mode to que up the next game for when you reboot to 3ds mode , you could use the ds mode to flash a new rom to the ram ,but can this use sd memory or not?
i wonder cause if it could then why do we still see expensive flash carts ,like the one for n64 which does not use sd ,i dont think it does anyway
it could still operate the same way and load through the 3ds menu screen but you would just reboot after using ds mode to reflash the rom you want to run in 3ds mode , also might as well build in a ds mode flashcard in to it too

why would they bother with people like you. no offense.. but they got better things to do like work on the card?

how would you get back to ds mode if the crown3ds did do this? I could only think of a switch on the cart to reset it to ds-mode, which could become a nuisance if you have your finger over the cart while playing (sometimes I do) and accidentally switched it to ds-mode, which would freeze the 3ds game (or bring up "Game Card Removed" either one would happen) and that wouldn't be good if you didn't save beforehand. Also you couldn't decrypt a 3ds rom in ds mode so the BEST you'd be able to see from a file list (to scroll through/select a 3ds rom) would be the FILE NAMES of the Roms, not the decrypted name or icon. Not that that's a huge problem, but it's something to consider. (ie if you named a Splinter Cell ROM XYZ.3ds you'd ONLY see XYZ.3ds as a header for the DS mode rom flasher/switcher, not Splinter Cell...blah blah)

I think you are underestimating what Chinese factories are able to do overnight. They could set up a layout in a few minutes and produce and populate the PCBs in hardly any amount of time. For an example, look at how fast the 360 reboot glitch chips have been produced by so many 'teams'.

or, they could configure the card to only read the state of the switch at the time of system bootup?

Anyway it could be much easier done in software:

Check if '3DSmode' is set
---YES:
------Unset '3DSmode (so next boot will be DS mode)
------Boot cartridge in 3DS mode
---NO:
------Boot cartridge in DS mode, user the selects ROM, '3DSmose' is set to on and the system is rebooted

I fear that it won't be a card, but cart instead and will be so bulky with 3DS card reader in it. If it uses a real 3DS card to bypass the security check and then loads the rom from a memory card. In that case the LCD screen idea is not bad at all.

About the "price".. Ppl are complaining even when we have no idea of the real price.
In my country the latest 3DS games costs $90 each (that's a big bunch of money). In the old GBA days the first flashcard cost me $600 shipped to my country. So I laugh at ppl who say $99 is much for this device!

Btw.. some pages back you talk about PSP movies on UMD discs. Those cost more in my country than DVD's and Blu-ray's, so it died pretty fast before it even got known.

they said that each cart has about 8gig of memory per game - thats my point as well for why they can only load 1 game at a time, not many people can afford over 16gb micro sd cards an that would only be 2-3 games max! for flashcarts to become commercially viable for the 3ds then high end sd cards will have to decrease in price alot!
That's pretty huge, I really need to think about to buy the games in a store then

You are mixing Gb and GB. Bits are not bytes. To help you, 8 Gb is only 1 GB (gigabytes). And that being the 1GB is not huge in these modern days with HQ graphics and sound effects with possible in game movie clips.

^FIRST POST AND NEWS ARE A BLESSING FOR THOSE WHO READ THEM.

PEOPLE WHO HATE THOSE WHO DO NOT READ THEM ARE NOT A BLESSING FOR THOSE WHO DO NOT READ THEM.

No one has tested it except for the developers and no release date. If you really want to be lazy. >.>

There's too many questions about the final thing when clearly there is not even a 'product' anywhere close to complete yet. Right now the Crown3DS doesn't exist frankly.

Helper said:
Before I start, yes, I realize this is pointless conjecture. To be fair, at least I'm not talking about how piracy will kill the 3DS and kittens and love.

If this is legit, and the method they (Crown3DS team) use is revere engineered, and the 3DS cart interface is sufficiently understood, and a 3DS game image can be unencrypted, I'd think it would be possible to intercept communication between the 3DS and the card. If you can intercept communication (in an unencrypted form), you can trap reads from specific memory addresses. If you can trap memory I/O, at the least you can in the 3DS's head. If there's a giant enough of a security hole, perhaps it would be possible to inject code and/or data. Of course, then the trick would be compiling 3DS code in the first place, what with there being no working toolkit, not to mention not even knowing all the specs of the 3DS.

Okay, now that all my lunacy is out of my system, I'll go back to my corner.

Thanks for one of the only relevant posts actually discussing the possibilities of the tech. Anyway what i think is, the communication that can be intercepted is things like the cart read functions and i suppose 'low level' stuff you might call it? But as soon as it gets onto the game it's going to be encrypted... so the only code you are running is on the cart itself. Now there must be some trick to even allow it to do that as i thought the RSA thingy would be checked before anything else. As said by cracker it seems as if it possibly uses an actual chip related to security/cart control or something and just boots a different game with it. But whatever you can do you can only control whats on the cart and respond to what the DS itself is asking you. The game data will be untouchable.

Which is why i wonder how saves will be handled when you can't intercept or patch the game on the fly or anything. I suppose the DS still has to communicate to the cart controls in unencrypted data 'hey we want to store this data on the save chip' and if you have control over the cart you can spoof everything needed to put it on some generic storage chip. That sounds like a lot of work alone though and needing to try out tons of different games and make sure you account for every type.

I see someone pointed out there's no CIC like security chip though. But couldn't the cart controller chip itself do some similar kind of security things? Like i'm just assuming there's 3 chips on the boards, the 'controller' and the save ROM and game ROM. Knowing Nintendo i'm guessing it's the same as DS except just assuming the new RSA won't be hacked.. but i don't know where any info on the DS carts are either to have a look at.
