RCXSimulator is very slow

[Alexander207]

When I press any of the buttons on RCXSimulator, the display takes a REALLY long time to refresh.

Is there any reason as to why this is happening?

Yes, that was what was meant by the comment in a post on the other thread that it was not as performant. From what I've gathered thus far, it appears to be due to how the timing is simulated, and even at that, the timing is noted on the university site to be not quite precise enough to consistently, successfully download firmware over the virtual IR connection. Apart from attempting to modify the decompiled code (which lacks any of the source code comments that might have existed in the original code), there's not much that can be done here.

If you'd like to contribute to some of these projects under BrickBot, you are welcome to do so. For items specific to just RCXSimulator, I would suggest posting under that project instead for better tracking within the project. :-)

It would be great to have the performance of brickEmu with the user interface of RCXSimulator. Interestingly, the last release for both was around the same time—RCXSimulator was on April 18, 2006, and brickEmu was on June 6, 2006.

Maybe create a new RCX pBrick emulator?

Are you volunteering? ;-)
