Your best bet is to hit-the-hardware, the registeres are well documented, and includeds are readily avaiable.
If you do a google search you wil find plenty of example code.
Also you can learn Amiga programmers best friend... the "shortcut" :lol: Try and figure out how to do something that looks like it requires a 90Ghz CPU and several Gig of RAM... but really is nothing more complex that a simple blitter copy and a dodgy copper list.
