Re: Thinking about multi-threading...
How often do you have to sync the cores anyway? That is, how fast can some sync event, or any change of shared state, propagate from say the VR4300 to the RCP? Suppose that takes 10 VR cycles, couldn't you then record every such event in the VR thread for 10 cycles, and if any happened in that batch...

Nothing is rendered
As the excellent description in the title says, I don't get anything rendered in the window. I poked around a little, and it turns out that in vi_cycle in vi/controller.c the variables hres and vres are always 0, which is because vi->regs[VI_H_START_REG] and friends are always 0 because they never g...

Re: How to Compile Cen64
Just wondering: which repo is the current one? CEN64 or CEN64-backport? Both got commits recently. And wouldn't it be better to have the backport simply as a branch in the main repo?

Re: A lot of asm? What about ZSNES situation? No const?
I'm a bit confused, I thought the SSE instruction set provided exactly the IEEE 754 floats except for a few rounding modes.
So where is the advantage of using the x87?
And where is the difference from e.g. an x87 float add to one on the VR4300?
