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!

If it's not already in there I'll look into it! I was mostly concerned with getting SGB borders loading properly so I hadn't paid much attention to the other Super Game Boy features.

After looking into the development of mGBA and why this isn't an upstream feature, I wouldn't chase after it. It essentially would involve emulating the SNES's sound engine at the same time as the graphical engine of mGBA. The only real workaround would be to do what SNES9x does and emulate the Super Game Boy as a proper SNES game, and that wouldn't be mGBA, would it?

Anyway, after testing lots of games across the three systems, it works great.

Kirby Tilt n' Tumble works fantastic and the SGB enhanced games have their special borders and colors, which are two of the things I look for most in an emulator like this.

Two minor notes:
- ~~The sound is a bit funky, especially on GB/GBC games, this seems to be an issue with mGBA itself, but it's worth looking into if you have the time/patience.~~
- As I mentioned, Kirby Tilt n' Tumble is fantastic, but I would love if the GBA motion control games worked too. I haven't tested Yoshi Topsy-Turvy, but WarioWare: Twisted! doesn't work.

Great work so far! This is already my preferred way to play GB* games on the Wii now! <3

I didn't see this before my main reply, sounds good!

I'll get to work on this later today. I'm really enthused about this project and would love to have it on my home screen too. I'm planning on using SNES9xGX's forwarder as a base so it fits the visual identity.

I've uploaded a full-resolution png of the mGBA-GX logo to the GitHub repo for those that want to use it for channel creation and such
