Hmm... my 1500MHz OWB computer plays them smooth, beautiful. But CPU is at the max... in general it's pretty horrible how the overwhelming CPU power is wasted on the web nowadays 
This won't be the 1st time that something originally from an Amiga (7mhz?) cannot easily be done on a more modern machine.
Similar to some of the Demos that have to be converted to video for the YouTube generation to view. All the horsepower to now run something that used to run from a floppy, back in the day
