Hacking Do 16/32/64GB SHDC cards work with M3 DS Real?

[Fel]

Without any menu lags or slowdowns in games?

Also can the Ysmenu still run from the M3 or is it fine?

Size shouldn't matter. This goes for any device with a SD slot, as long as it supports SDHC.
In the old days it used to be the case that smaller (1GB and 2GB) SD cards worked better, because the SDHC cards had slower speeds and there were a handful of smaller cards that were recommended for compatibility reasons because the larger cards were too slow causing issues in certain problem games, and even many of the smaller cards were too slow, but SD cards are much faster now so that's no longer a problem.
Formatting the card with a larger cluster size (32k or 64k) will improve speeds a bit.
If you have a lot of files in one folder it might cause slowdown/lag in the kernel menu. Might be a good idea to separate the games into folders by letter if you have a lot of them.

Thanks! I have a 8GB SDHC card class 6 that works well, however after having less than 500MB space on it Etrian Odyssey 3 started freezing on Sakura (but not Ysmenu) during battles, so I was wondering if a 16 or 32GB upgrade would be as good. Do you think a faster class could perhaps make games play too fast, like it happens in Dosbox unless you change the cpu cycles, or do the games have a FPS lock?

Higher SDHC class speed doesn't make games run too fast, right?

First, class is sequential write speed - the spec that matters the least for gaming

DS software, at least early ones, is directly tied to the system's performance (which is why the GBAccelerator and XCM Lite were a thing) - but performance of storage, not so much (not only are original DS cards relatively slow compared to its predecessors and successors, but I haven't heard of flashcards actually cutting [small and likely processor-bottlenecked] loading times - though if you play Pokemon the "saving a lot of data" may get a visible improvement )

Edit: I was thinking of the M3 Simply. SDHC should be fine on this.

Pretty sure the M3DS Real will only read up to a 2GB Micro SD. Iirc, it couldn't read SDHC at all.

Not true, you're probably confusing it with the M3 Simply/Perfect. M3DS Real could use SDHC , I actually own a M3 DS Real with a 8GB card (I've mentioned it in a post above you).

Thanks! I remember people were saying the class does affect some games, for example the intro in Castlevania lagged on lower speeds and some people even reported having game freezes etc., and it was recommended to buy class 6. I don't think I've ever heard of it working inversely (the highest was 6 or 8 back then, not sure) - higher speeds making games load faster, however if you had lower class, some games might've had freezes or lags. However since now we've got class 10/12 I thought I'd ask just to make sure.

I only own a legit Pokemon card, has it been tested if Pokemon are faster? If yes, that'd be cool, although it only takes a few seconds on my PW save, so I don't mind at all.

Read speeds influence loading, while a card that's faster at sequential writes is also (usually) better at sequential and random reads it doesn't have to
