No not really. A small part of the CPU's time is dedicated to setting up the VIP to draw. If it had to draw two completely different screens then the worst that would happen is that the rendering code would take twice as long, but that wouldn't be half the time in a typical game. The remainder of the frame time is used by the CPU to do things like game logic, sound, etc. that are independent of how much is rendered.

Headphones are headphones. As long as they use the standard 3.5mm plug as most consumer audio equipment, they'll work fine with the VB. I use my Sennheisers when testing my audio code.

Derp. Looking at the v810 architecture manual, you are absolutely right. On the bright side, that's one less bug to fix in GCC. :)

One of the members here already started on an implementation of LLVM/v810... Maybe it was Parasyte? dasi? As I recall there wasn't much progress on it.

v810 support hasn't been in GCC mainline since version 2.x IIRC. I got the 4.4.2 patches from dasi; perhaps he wrote them originally but I honestly have no idea. I think the v810 patches are largely based on existing support for the v850, which is similar.

The 4.8 patches are part of "devkitV810," which as far as I can tell is just a fancy name for GCC + some auxiliary tools. It's supposedly being worked on by dasi and/or Guy Perfect, but I haven't seen or heard anything from either of them regarding that project in a long time. I think they might be floating around out there on a Git server somewhere...
