"SURPRIIIIIIISE The beta release of our Grand Theft Auto Vice City port to the Sega Dreamcast is finally here Here's an actual hardware capture of raising some hell in the beautiful streets of Miami taken straight from my DC to celebrate We've now added graphics settings for 2xFSAA to give it a less jagged more smooth look and have added a video mode for rendering to a 24bpp framebuffer which adds extra depth and vividness to the colors While we still have plenty of work to do regarding features assets and performance I am extremely proud of our team after what we've accomplished within just a"

"FINALLY got the inline SH4 assembly worked out to create a permutation matrix which swizzles XYZW vertex coordinates into WXYZ ordering on the Sega Dreamcast .why in the actual eff would ANYONE want to do such a thing Well I've been told this is an old Sega trick and the reasoning behind it checks out. When transforming a vector by the "active" matrix held within the XMTRX FP register back-bank the god instruction FTRV is used on the DC's SH4 CPU. FTRV has a single issue cycle and 5-8 latency cycles while it propagates through the pipeline producing transformed coordinates starting with X at"

"I can point you to an extremely prevalent prominent example of this not being the case: GTk and the entirety of the GNOME stack. and I mean no offense to them as a desktop UI library and cross-language framework (GObject) are a little more complex than having no abstractions and no heap allocations. lol"
