Just compile Fix94's haxchi.
It works for both the US and EU version of Brain Age.

Well I modified FIX94's code to boot cfwbooter instead. Although @Maschell made a version that boots to either cfwbooter or HBL depending on a button press, I wanted two separate versions. That way when FIX94 (hopefully) backports to Kirby, I'll be able to have both a HBL and redNAND icon directly on my home menu.
Next I'll figure out modifying meta info for icons/images, meta.xml for the name, and then the last thing I'll look into is how to modify/create btsnd files. I'm assuming I'll need the Wii U SDK if I want to do that though, and I would love if someone could verify that.

I just spent far, far too much time working on more haxchi, it now can load the homebrew launcher if you happen to own brain age, kirby squeak squad/mouse attack or yoshis island ds!

This really was quite a LOT of work to get done in some reasonable fashion, so dont come at me and ask if I can port it to other versions please, it was a lot of work already.

Nice now I think I'm going to buy a game...the cheapest one of course

Alright so this is a quick video that shows Kirby loading the HBL from a cold boot
Good job FIX94

 

[TheCyberQuake]

And @FIX94 just added support for Yoshi's Island and Kirby, both PAL and US
Edit: welp my internet derped and an entire page of posts didn't show up so I'm late to the party -_-

I'll just install it in the pirate version and use it as a homebrew channel in CFW

Thanks both of you @FIX94 and @Maschell

Can someone point me in the right direction on how to create custom tga images?
Edit: NVM, just found out Photoshop can directly open and edit tga files.

 

[TheCyberQuake]

So far so good with my redNAND launching modifications. I'll probably share all my modifications once I'm done (if that's not allowed for some reason let me know). Just have to work on other images and then the boot sound

Delete the save file for the game, then try one more time.
