<p>Definitely not. The WBFS/SD methods of Legacy XP run just fine and much faster than on Wii/Dolphin SDHC. Some of that is to be expected because more of it is loading from the WBFS, but stage alts and clone characters still appear to load much faster.</p>

<ul></ul><p>Alright, I decided to actually time the loading times to a decent degree. I noticed that the slowdown only seems to occur when you add more than 2 GB worth of files. That is, the same build of Legacy TE (< 2 GB), inserted into any sized virtual SD card, will not have any slowdown. However, Legacy XP, given its size, is where the problems start to show. </p>
<p>Match load on 64 Battlefield:</p>
<p>Real Wii, Sandisk Ultra Class 10 80 MB/s: <strong>~1.4 s</strong><br>
Dolphin 5.0-5491, 8 GB vSD: <strong>~2.7 s</strong></p>
<p>Note that I have a pretty fast SD card -- I got it specifically because another one I had had terrible read speeds. I definitely wouldn't know what the Wii's SD card read speed limit is, but it's clear that whatever timing Dolphin is emulating (intentional or not) isn't necessarily Wii-accurate. </p>
<p>Once again, the biggest issue is the streaming music on the menu that stops because it can't read fast enough. On the Wii, no such problem exists on my SD card.</p>
<p>Thanks for looking into this, guys!</p>

<ul></ul><p>Well, I'm fairly sure we don't emulate any timings - so we should be faster. The fact we're not could be indicative of really, really bad problems.</p>

<ul></ul><p>When we get accurate SD timings, options should be added to the INI to make the relevant variable(s) easily editable. Mods like BX CSS Expansion v2.0.0.x (<a href="http://forums.kc-mm.com/index.php?topic=65113.0" class="external">http://forums.kc-mm.com/index.php?topic=65113.0</a>) would probably benefit from faster-than-console read/write times.</p>
