Advent, I think you're talking about PSP-Programming.com
Hi aditya258! Welcome to the site!
PSP-Programming is great but if you're not skilled with C or C++, then you can always use LUA for PSP development. A lot of helpful LUA coding tutorials can be found on EvilMana.com
Both sites have really helpful tutorial sections. I'd suggest checking them out!
Are you wanting to develop for the iPhone? YouTube has some awesome tutorials. You need a Mac with Leopard and an Intel Processor to run the development studio.
What do you want to program for and what are the languages that you're used to using?
