Is SA1 SRAM 2Mbit or 2Mbyte?

I've been reading the second of two snes manuals and in this book it first states that the SRAM on a Super Accelerator System is 2Mbyte, but later states that the maximum is only 2Mbit. I assume that either I'm misreading something somewhere, or that the 2Mbyte is a typo, as the fullsnes doc only ha...

Re: Looking to make an SA1 Dev board

I may be being a complete idiot here, but may I ask why you'd want a revision above -10? I thought all the boards have the same kind of stuff on them with the same code, and so revision wouldn't matter?

Re: More complex mode 7 rotation (z-axis+others)

So I've been looking at this by messing with a plane in the 3D modelling software Blender, and I don't think there's actually any angle where the rotation can't be defined as a set of scanline strips of a matrix transformed plane. However, I very well may be wrong. Nicole: Yes, exactly. tepples: I d...

More complex mode 7 rotation (z-axis)

Hey guys, So I've been thinking about how mode 7 works and the ways which you can rotate the background. It's pretty trivial to rotate about the x-axis by changing the matrix values. It's also somewhat easy to rotate about the y-axis using HDMA and stuff. However, I was wondering if there was a good...
