Over the last few months I’ve pieced together various snippets and hints from the web to come to the conclusion that Microsoft’s forthcoming XNA platform, specifically the XNA Framework version, would be available to home-brew developers and let them develop on the Xbox 360 — the first official home-brew since the PlayStation 1’s Net Yaroze!
Indeed I’ve been telling people in IRC and on forums that I believe this to be true. One friend, after messing with Managed DirectX2, told me if I was wrong about this I was in trouble. I went as so far to claim that it’s already tested and GarageGames Marble Blast Ultra was an XNA Framework title.
