Development programs?

[rouken]

I got a doubt this week about how to develop programs for Dreamcast (not I will program someday, but just for my curiosity...). I thought to myself "if Dreamcast's programming runs under a Windows system, so it's easy to do a program in PC under Windows and convert it to Dreamcast". But, I got other thing in mind: The Dreamcast Development Kit, a kind of PC-Dreamcast hybrid specific to develop games (and other programs) to Dreamcast.

So... There's the question: If someone want to create some kind of program/game/etc to Dreamcast, the need of the Development Kit is imperative, or you can use some kind of development tool for PC?

Another question is: If a Development Kit is imperative to create such thing, what is the average price of a Dreamcast Dev. Kit? If you find one, of course...

To SWAT: Do you program the DreamShell with the help of this development kit? If yes, can you post one pic of your Dev. Kit?
