If you mean qCube: http://mzrg.com/js/. If you mean Iso: http://mzrg.com/rubik/iso/. About changing cubes on jflysim: the type of puzzle is in the timer options; the dimensions (LxMxN) can be changed by clicking on "options" in the sim and then changing dim_x/dim_y/dim_z.
Smerbia is better. All hail Smerbia

Don't worry about me being a little bit faster, it's swim season and I don't have much time in the week to cube. Plus, your brother can help you out. As far as I know I'm the fastest cuber for miles unfortunately. Either way good luck, I look forward to a good race.
