Trying to use GC2SD Memory Card with Swiss, getting "Failed to read BS2!" error

[PowerBounce64]

Hello! I recently just purchased a GC2SD Memory Card so that I could use Swiss on my softmodded Wii. I was intending to use it to play Super Mario Eclipse, because that hack's custom music doesn't work when trying to play it using Nintendont. I think I had gotten everything set up: I downloaded the as of now latest version of Swiss (v0.6r2018), installed the .gci version of it onto my official GameCube Memory Card in Slot A using the app GCMM, installed the Wind Waker exploit .gci onto the same card, loaded my physical copy of The Wind Waker to activate the exploit and boot into the Swiss menu, and then open up the GC2SD Memory Card in Slot B with the game on it, which was correctly recognized.

However, every time I try to load the game from the GC2SD card, it says "Failed to read BS2!" and then stops. Nothing else happens, as in it doesn't make Swiss or my Wii reset or crash; Swiss just doesn't open the game. I've tried looking online for help about this, but I haven't been able to find much of anything about issues with BS2, and the sole posted topic on this website's GC Modding forum (viewtopic.php?p=51051) only talks about it context of the SD2SP2 instead, which is *not* what I'm using. Some of the advice I have found mentions that the Micro SD Card should be FAT32, which it is, and have 32KB clusters, which it does.

For the record, while in the Swiss menu, I decided to try loading the official Wind Waker disc that was already in my Wii, and it was giving me the same "Failed to read BS2!" error, despite being the original unedited version of the game. So it doesn't seem like whether the game is modded is the issue.

Is there anything I can do to fix this specific issue so that the game can load?

Turn off "Load GameCube Main Menu", or provide a ipl.bin in /swiss/patches.

That worked! Thank you so much!
