Calling all Coders/ Those with knowledge of C,C+ and SH4asm

Lots of us in the Dreamcast scene would love to learn how to program and code and maybe one day produce something for the Dreamcast scene ourselves. So lets see if we can get the ball rolling with this request from Turrican 2k:

“Seeing as there’s a lot of people getting into Dc coding with the aim of porting apps/games/emus to the DC it would be nice to have a few donations of simple tutorials of how to start and what lines to start to port when doing a DC port. A commented source code with what was changed to suit the Dc would be great “

if anyone can help please post in either this topic on https://dcemulation.org/phpBB/viewtopic.php?p=128245#128245 or this topic on http://cvforums.wolfnet.org/YaBB.cgi?board=dcdev&action=display&num=1029011661
