What's the state of Genesis homebrew versus other consoles? Is there much of an active community? I can't seem to find many resources online, especially any that are recently updated.

Any links or info are appreciated.

funny you should ask, I've recently gotten interested in genesis/megadrive too (mostly because of the FM sound). Haven't really started coding anything yet just tried to create a simple rom really, but found some material to read:

and this is the assembler I'm currently using (had to find something that supported OS X in my case):

Excellent, just what I was looking for. Thanks.

Three letters: GCC

yeah, but I've never liked GCC assembler syntax.. it just feels so wrong :s (although I've not looked at it in a while, might have changed my mind)

There are three ways to work around this:

• Write a preprocessor to convert your preferred syntax into GNU as syntax.
• Use such a preprocessor that someone else has written.
• Use a different assembler that outputs the same object code format, so that you can still combine the object codes using ld. Several x86 projects use NASM, for instance.
