<b style=\'color: #ff0000\'>Please note: this guide has been written in 2003-2004, when I was learning the intricacies of Megadrive programming. As a result, there are some errors in some pages and in some sample source code. I advise caution when using this guide. Also, my English language... prowess wasn\'t that great back then so forgive the bad grammar.

Somewhere on my to-do list is a complete rewrite of this section and a much better MD reference, but until then, I\'m keeping this online. And for nostalgia, of course. <i>(Note added in 2009)</i></b>

Welcome to my 68k programming guide. You will learn about the basics (adding, substracting etc.) as well as more exciting things, like editing objects in Sonic engine or even programming your own ones =P

<b>REMEMBER:</b> If you don\'t understand something, you are lost, you have comments or you\'ve seen some errors (hmmm =P), post it on the forums. I\'ll not only help you, but I\'ll improve and make my guides better (I know they aren\'t great XD). And one note: Don\'t worry if you don\'t understand something, it\'s not the end of the world. This is assembly, it\'s not easy...

Have fun =)
