While I was working on my PlayStation Mobile book I didn’t produce all that many PlayStation Mobile tutorials. I guess it was a matter of PSM overload in a way, although you should expect to see a few more in the near future covering things that have been added since the book was released. The good new is, there is another developer, Alex McGilvray, that has created some great PSM tutorials! His series of tutorials are a bit lower leveled than the ones here on GameFromScratch and are a good compliment.
He has made the following tutorials:
Tutorial 1 -- Getting Started
Tutorial 2 Part 1 – Shader Programming
Tutorial 2 Part 2 – Vertices, Indices and Vertex Colors
Tutorial 2 Part 3 – Texture Coordinates
Tutorial 2 Part 4 – Vertex Buffers
Tutorial 2 Part 5 – The Render Loop
Tutorial 3 – Improving PSM Rendering Performance
Or you can just check out his blog. Nice work Alex!
