Thank you for the update. When will we get to see the finished product? I work in game development and I'm looking forward to your next steps.
If you meant the book as a finished product, that will take some more time as I need editing help. I have started talks with chromatic so it is not too far off. However the grant itself is close to finishing I am closing it as I type this.
If you meant the code the newest release of SDL will be good enough to use.
The current manual can be picked up at
