Current AO progress is:

Overall Complete functions: ~99% (See below)

Overall Complete instructions: ~99%

Hello all,

We are nearing the endgame. The reversing project is one step from releasing a standalone version of AO’s engine and thus providing the same boons as the AE version does. While there are still some bugs that need to be fixed (for instance the audio currently completely refuses to work and the input has problems too), you can nonetheless expect AO to drop in the upcoming months.

With these happy news out of the way, it’s time to take a look at this month’s “whodunnit.” Like always, you can click on their names to see every single git commit they made along with the code in these commits. And now strap yourself in, because there are a lot of changes and additions to go over:
