In games Saves not working on Wii

[average612]

Hello mGBA forums I've tried googling this to find a fix for it and haven't really come up with much so I'm gonna post here. Been recently using mGBA to play Fire Emblem Binding Blade and the emulator works very smoothly on my Wii. My laptop is very lack luster so it has issue running even GBA games which I still experience audio cracks on even in mGBA, so the Wii is my best bet. The issue itself is that in-game saves are creating 0 byte files with no data on them. I even added the directory under ports.wii and created a folder for saves to be held, and while in-game it appears to be saving, my SD card just has empty .sav files. Save states do work properly, but I'd rather use GBA saves to rely on. I used the same rom and was able to reload and create a legitimate save file on my laptop using mGBA so the rom isn't the issue. Anyone got a clue?
