Details

This patch contains several improvements to the Chopper game designed to make it run with a high framerate instead of a low, jerky one. Previously, the game depended on sleeping for a number cycles before drawing another frame, causing very jerky motion. Now the game should run at a high framerate all the time. The gameplay should be about the same, at least on targets with a display of >64px. I don't have any of these smaller targets, so I wasn't able to test. Please tell me what you think of my changes.

The game runs a lot faster with this patch. While I think a patch that increases the framerate would be fine, I don't think doing this at the cost of upsetting the game balance is acceptable.

Here is a new version of the patch that decreases starting speed in normal mode.

I've been using the second version of this patch for quite some time now, and I thought it was great in my initial testing and semi-frequent usage from then until now, but I have only just now used it while listening to music also and the gameplay is terrible. (Using Nano2G)
Have you (mamarley) tested this while listening to audio also?
The game speed seems really jumpy and eratic, quickly going from super fast to a little more than a crawl and back again...<wild speculation>presumably while the CPU is boosting/unboosted.</wild speculation>
