Great work team, let me give this a try

Can somebody create an awesome channel on the WII home screen for this?

When you select USB as your main device, the software is not able to find the USB drive, I found this also in version 3.0.0 but this was still working in version 2.4.8 which I currently use on my Wii. If I select USB mass storage the software is unable to find my HDD. This HDD is found while using version 2.4.8 and other emulators like USB loader GX, SEGA, Atari etc.

Have fun

Thank you everyone for your feedback, it's greatly appreciated and I'll take a look at some of the issues brought up here in the coming days. My main fix to the audio in the last release was specifically at framepacing issues when not running at 59.976hz, but I'm gonna take a closer look at how specifically GB and GBC audio is decoded and interpolated.

About the Boktai freeze when the classic interface is enabled, I have an idea on why that's happening, so I'll try to tackle that too in the next release. I've never played the Boktai series before, so when I was originally making this for my personal use it was not high on the list of priorities. And for the save file generation, xunga's suggestions are completely spot-on and I will definitely be taking those into account for the next build. Oddly enough I didn't think mGBA would need a frameskip option for most use-cases but hooking the feature back into GX's interface shouldn't be too difficult.

As for the HDD issue someone mentioned, I'll look into that too. It's interesting that most apps are able to detect your harddrive but others aren't so it's probably something on mGBA-GX's end that I can remedy.

I am so grateful you are all sticking with me through this process. I am by no means a seasoned developer, and learning CPP by developing for the Wii isn't the most practical way to do it. But it means a lot that people are enjoying the project!
