Wii U Retroarch abnormally slow file access

[draculaxx]

Hi team. Please be aware that WiiU Retroarch suffers from slow SD file access when loading cores and/or roms.

For instance : -with everything installed on SD card: launching Retroarch takes almost 30 seconds, loading a big rom (>20 MB) takes almost 20s.
-When using the vWii version (Retroarch-Wii), with everything installed on FAT32 USB : launching Retroarch takes less than 7s, loading the same rom takes less than 6s...

So it may be suggested to create a USB installable RA for the Wii U.
Thanks very much.

I'm assuming this is a regression because it was not that slow for me before, even on SD. Have you tried a different SD card in case that's the problem?

I do think it has always been this slow.
Updating assets never really succeeds because of this.

I do not know enough about WiiU homebrew to know if this is a global problem or not, and I don't really know if you can use the USB HDD for homebrew either.

Thank you @bparker06 and @fr500. Indeed I spent the last night testing different cards.. and it is noticeably slow with any sd card. Thanks.

I'm having the same issue.
