Yeldarb who is one of the PSP Scenes leading figures for tutorials for Developers has released a new Tutorial, heres what he posted:
I just finished the fifth installment in my PSP Programming Tutorial Series. This lesson teaches more programming methods, such as overclocking, switch structures, colors, and graphics-based text. The tutorial walks the reader through creating a background-color changer, thoroughly explaining each step. The tutorial series is great for everyone from a newbie who has never programmed in his or her life to an advanced programmer looking to get a start in the world of PSP Programming. There is also a new RSS feed on the tutorials, allowing you to stay up to date with new releases.
