Oh boy, a callout post!
Everything's coming along well. Userland UI is getting locked in and we're starting to implement those features. In the last few days I've personally done a heap of RE to unlock a bunch IOS-side resources for use in PPC homebrew, as well as mostly rewriting our entry code from scratch to cut boot time (by like 15 seconds!) and get stability up to 100% under all conditions.
Tangentially related - debugging is a breeze on our stuff since you can get very verbose post-crash logs even after the entire PPC-side system has seized up. We're super excited to get that functionality in developers' hands.
Here's an example of some random browser crash I still have open in notepad++ as an example. We've actually fleshed out logging with our own additions too, but we'll talk more about that later.
Sorry things are taking so long, but the good thing is we're definitely starting to get a good grip on exactly what still needs to be done still before we can release!
