PVR Resolution?

In all PVR demos, there is no setting of resolution in any of the examples. Does it just default to 640 by 480 with 16 bit depth?

Check pvr.h in kos that will tell you.

Default is 640x480, 16-bit (RGB565), 60Hz

would be easier for homebrewn games to be in 32-bit depth seeing that SH-4 carry data in 32-bit chunks anyway and plus the game spends less time converting colors and such. or do the color depth the way SH-4 have nothing to do with each other?

Not really. If a (2D) game doesn't use RGB565, it tends to use 24-bit, or 8-bit paletted modes. Either of those would need to be converted anyway.

One of the advantages of dreamcast powervr over other graphics hardware is that 16-bit framebuffer on powervr looks just as good as (if not better than) 32-bit frame buffer on conventional hardware. This is because powervr does colour calculations internally at 32-bits regardless of framebuffer depth.

As such, it is faster to use 16-bit framebuffer and you still get the 32-bit quality.
