I think screen rotation would be slower than the 1:1 code because it probably has to be drawn one pixel at a time. But it wouldn't be hard to do. Is gigabeat always rotated on rockboy?

You mean the menu in rockboy? I guess quit is the only option I've tried, and I know it works. I haven't personally done anything with a menu in InfoNes, and I didn't know there was one. There are a few dummy functions but I don't think they do anything. I was going to work on that later tonight. :)

I was talking about the dummy menu in infones. There's an option to rotate in rockboy, and it's rotated by default on mpegplayer. I think rotation is done in the LCD controller, because I don't think that there's any loss of speed in rockboy when it's turned on. maybe look through the cod eand see what's up. I tried, but couldn't find/understand it.
crzyboyster:
So it seems that the NES emulator is really making progress. Can I expect to see this released in svn by late november or early december, or any time at all? ;D Thanks for making rockbox even better.

Do you have sound working yet? I haven't tried your patch.
MikeT:
No, no working sound unfortunately.

The rotation code is in lcd.c starting around line 830. This is similar to the way that it is done in doom as well. It is not performed by the controller, but it is very fast. It is using fixed point calculations to scale and rotate based on the source and destination screen sizes.
