Emulator Issues #10514
open
SDHC read times are very slow
0%
Description
Game Name?
Super Smash Bros. Brawl / Project M / Legacy XP
Game ID? (right click the game in the game list, properties, info tab)
RSBE01 (RSBEXP)
What's the problem? Describe what went wrong.
The new SDHC update got Project M builds larger than 2 GB up and running. However, as soon as the 2 GB limit is passed, file read times become very slow, more so than on a real Wii with a fairly high-end SD card. It's severe enough to the point where music streamed continuously from the SD card (e.g. on the Character Selection Screen in Legacy XP) will often stop as it tries to load the rest of the song.
I'm almost certain this is related to issue #10461 (https://bugs.dolphin-emu.org/issues/10461#change-730393) about the "Receiving vault data..." message -- my guess is that Brawl makes the message pop up if it takes longer than an expected amount of time to read Vault data from the SD card.
What steps will reproduce the problem?
Create a 6+ GB SD card file and follow the Legacy XP's install instructions (http://forums.kc-mm.com/Gallery/BrawlView.php?Number=212860) as if you were doing so on a real Wii, but of course setting Brawl as the default ISO and loading up the Legacy XP launcher included in the download. Open up the game and play around, especially on the CSS.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Yes. 5.0-5352
If the issue isn't present in the latest stable version, which is the first broken version?
5.0-5044 is the build number for the SDHC support merge.
What are your PC specifications?
i5-750 @ 3.0 GHz, GTX 770, Windows 8.1, tried on both an HDD and SSD
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
I included small video showing the SDIO logs on the CSS (no idea if this helps, haha).
