Support the SDHC protocol for Virtual SD cards larger than 1.95GB
0%
Description
Game Name?
Super Smash Bros. Brawl
Game ID?
RSBE01
What's the problem? Describe what went wrong in few words.
If >1.95GB of data is added to sd.raw for a Brawlex setup (http://forums.kc-mm.com/index.php?topic=65113.0), File Patch Code 3.5.1b fails to replace all files. This problem does not occur on my real Wii using an SDHC with the SDHC expansion 1.1 code (http://forums.kc-mm.com/index.php?topic=65342.0). Dolphin fails to properly read the sd.raw regardless of sd.raw size or SDHC expansion code presence as long as >1.95GB of data is on the sd.raw.
What did you expect to happen instead?
sd.raw to behave like an SDHC card
What steps will reproduce the problem?
- Use mksdcard to make a 4GB sd.raw image (I also have the same problem if I make a 3GB or 8GB image). The batch file in this archive has a preconfigured 4GB option (http://www.mediafire.com/download/713qu5m08tf8av9/mksdcard+menu.rar).
- Add any functional Brawlex setup that is larger than 1.95GB
- Observe missing custom menus and characters (usually associated with a "Read Failure" on Dolphin's log.
Which versions of Dolphin did you test on?
I believe this has always been a problem with Dolphin. I tested the issue with both 3.0 and 3.5 and experienced this problem. I tested again with Dolphin 4.0-7084 and thought a bug report was necessary.
Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No
What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Win 8.1 Pro x64
Intel Core i7-4702MQ CPU @2.20GHz
GeForce GT 750M

Yep, Dolphin doesn't emulate the SDHC standard.

It's been a while so I though I'd give this a bump. SDHC support would be a very important feature for the Smash community.

Also, the code below allows SDHC cards to be used with Super Smash Bros. Brawl on system menus above 4.1. The code does not appear to interfere with regular SD cards either.

Some further research on this topic,
These “Simplified” Specifications may be of help. https://www.sdcard.org/downloads/pls/
And according to this post SDHC isn’t too different from SD but is still a pain to implement. http://wiki.seabright.co.nz/wiki/SdCardProtocol.html
System Menu 4.0 introduced SDHC support for the system menu (http://wiibrew.org/wiki/System_Menu_4.0) and may have something to do with IOS60 (http://wiibrew.org/wiki/IOS60).
Also, according to Bero’s notes (maker of the SDHC code in my previous comment), System Menu 4.1 (or at least IOS58 installation) is required for the code to work. Some of his notes were not correct about the SDHC code however so this information may not be valid.
Additionally, HyperL!nk from KCMM indicated that Dolphin dev Billiard26 may have done heavy work with Dolphin's SD support.
