I'm thinking it'd be helpful if there was links to Newegg for people to purchase the working SD cards if they need one of them.

My Sandisk 256MB/512MB/1GB SD cards all say no entries when I push start to switch to SD mode.  I tried FAT and FAT32.

edit: tested on beta3, beta 4 and beta 5

Hey ChillyWilly,

Separate working from nonworking SD cards.

Example:

WORKING

SD cards
AData MyFlash 50X 2GB
Kingston 256MB
PDP PATRIOT Signature Line 40X 2GB
PNY 2GB micro SD with SD adapter
PQi High-Speed 150X 2GB
TwinMOS Ultra-X 66X 256MB

SDHC cards
PNY SDHC 4GB
AData Super SDHC 2.0 8GB

FAILS

SD Cards
AData MyFlash Turbo 150X 512MB
Kingston 2GB
PNY Optima SD 2GB

This should be put on the wiki so other people can edit this instead of just you. The burden of updating this shouldn't be on one person. :)

I tried a 16MB Canon MMC but of course it didn't work and it stalled just like if there was no card connected at all.

The Neo2-SD can handle MMC, but there's no room in the code for MMC support. I was lucky to squeeze SDHC support in, mostly because it uses the exact same protocol as SD, just using block addresses instead of byte addresses. I'll work MMC into the enhanced menu.

@Nintendud - Good idea on the format. I'm not sure who's allowed to work on the wiki, but that's a good idea too.

If I remember correctly, the file system I use for the menu currently has a limit of 32GB.

If I remember correctly, the file system I use for the menu currently has a limit of 32GB.

32GB is also the current maximum size for SDHC cards.  While the theoretical limit of SDHC is ~2TB, the current specification does not allow for those sizes.

The new SDXC format has recently been introduced to provide capacity over 32GB. 

Fact is, there's no reason to have that much storage for the MD Myth.  You can have the full USA, JPN and EUR sets on a 4GB card.  Even if you start going homebrew crazy, I can't think how you could possibly fill up a 32GB card for this purpose.
Title: Re: Which SD cards work with the current MD Menu
Post by: Sektor on March 17, 2010, 03:16:11 PM
There is a limit of 400 something (forget the exact number) ROMs per folder, so you have to divide them up to hold them all. This is a menu/RAM limit and not a limit of the file system.

Thanks for the info guys. Got my RGB cable today so have been trying my cart out, couple of questions but Ill put them in their own thread:).

and ur right goldenegg, 4GB is more than enough!, unless someone figures a way to run megacd isos off the sd!.
Title: Re: Which SD cards work with the current MD Menu
Post by: ChillyWilly on March 18, 2010, 03:20:54 AM
I'll think about SDXC when you can get a cheap SDXC card at WalMart.  ~sm-65.gif~.gif

As mentioned, 32GB should be more than enough for now. Even with homebrew taking advantage of the SD card, 32GB is way more than the average person would use.

That said, if someone DOES provide a valid reason to do more, I'll look into it.

Hama 8GB SDHC Class 6

Although it is quite a bit slower reading from it than the carts flashram, is this normal?!.

LFN support is being added to the deluxe menu. And yes, SD cards are slower than flash. Right now, you get about 50 KB/sec transfer from the SD card. The theoretical raw transfer rate (discounting file system overhead) is a bit more than 100 KB/sec. The SD card has to be read by the CPU without any extra hardware support, which limits the speed. A 7.7MHz 68000 simply can't read an SD card that fast by itself.

Post by: churkus on March 22, 2010, 07:56:40 PM
Thanks for the explanation ChillyWilly, it makes sense. I guess it was never designed to be handling sd i/o!. At least its faster and more convenient than loading a 32mbit file spanning 3 floppies on my magic drive was!.

Looking forward to LFN support!.

Well, the flash carts were designed for a GBA/NDS. It's rather lucky that they also work as well as they do for the Genesis, SNES, and N64. If a clock source had been made from the MD Myth to the flash cart, we could have used the special cart feature that DMAs the SD card data into SRAM. That would have been given faster SD reading.

I know nothing about programming, so forgive the ignorance behind this question, but would it be possible for faster loading if the menu ran on a 32x and utilized its coprocessors?

Yes , that is correct.CW plans to work on it sometime.But don't except speeds like 200KB/s.The psram speed limit is like 150KB/s.  ~sm-82.gif~.gif

150? Are you talking about some SD-specific case?  The SNES menu copies games from GBAC to PSRAM at about 400 kB/s.
Title: Re: Which SD cards work with the current MD Menu
Post by: ChillyWilly on September 23, 2010, 11:25:18 PM
Remember that the fundamental speed limit is the rom access cycle time, which is a minimum of 8 cycles on the 32X, assuming no collisions with the 68000 or the other SH2. Given a 23 MHz clock rate, this means you get a maximum raw access speed of 23 / 8 / 2 ~ 1.4 MBytes/sec. So at least theoretically, we may be able to get some decent speed from a 32X version of the menu. I don't know if the MD Myth cart itself imposes some kind of speed limit on that, but given it works with 32X games without slow downs, I would guess not.

I guess I should probably do some tests to see how it actually works... maybe make a quick test version from the existing menu. Given the extra memory in the 32X compared to the MD, it should also have fewer limits as I don't have to try to squeeze things into 64KB.

Yes.I haven't ever tried to do timing tests from mem->psram or sram->psram and i have no idea about the rom access cycle time to give an estimation  ~sm-57.gif~.gif
A good example of this is the N64 menu..

I have not been on this forum in a while and I was thinking about purchasing a Neo2SD for my Sega Neomyth cart. I bought a 1024 megabit cart and it when I formatted it for sega it only gave me half the storage it claimed. So I am wanting to get the Neo2SD version in order to use a real SD card instead. So my question is if I get this and say a 2gigabyte Kingston SD card I can load every game I could ever want on to this one device without buying another one of those 1024 megabit carts? If so..... then why would anyone ever want anything but the SD card version?  ???

The current PC client doesn't handle 1Gbit cards right, which is why it limits itself to 512Mbit until the issue is resolved.

As far as cards for the MD Myth, you really don't need more than the Neo2-SD. Once you have one of those, you can run whatever you want off SD or SDHC cards. The only things you NEED to put on the flash are SMS games (unless you have the latest V5 MD Myth hardware, then those can also be played off SD).

SD CARD : EMTEC 2GB = FAIL (but works with NEO N64  Myth cart)

Let me guess :
It is a "slow-card".The n64 menu detects this , and the disk io code triggers a small delay for each op....
The MD menu doesn't do this , so ..  ~sm-36.gif~  ~sm-36.gif~  ~sm-36.gif~

But yeah  ~sm-36.gif~ , we can implement this on the md menu aswell...but it is always recommended to use quality sdcs since you'll always get a penalty
on transfer speeds...and you don't want that.

You want the Neo2-SD: http://www.ic2005.com/shop/product.php?productid=41&cat=5&page=1

Unless you plan to get the N64 Myth at some point, then you'd probably want to get the Neo2-Pro: http://www.ic2005.com/shop/product.php?productid=119&cat=5&page=1

The Neo2-Pro works for the MD Myth as well, but doesn't have any advantage over the Neo2-SD ON THE MD MYTH. You want the pro for the N64 Myth as it allows you to load games up to 32MBytes while the Neo2-SD is limited to 16MBytes.

Sandisk 4GB MicroSDHC Class 4 (with adapter)

NEO3-SD may corrupt written data in the SDHC card, making the card unreadable in Windows.

EDIT:
Please add to WORKS list Smart Modular Technologies 4GB Micro SDHC (with adapter). Works flawlessly.
