Thank you for sharing, it runs well in my emulator (the b/w version out
of the box, the color version needs a bit of patching the switches and

But most of the stuff shown on the screenshot (apart from the ticking
clock) I cannot find in the disk image. Trying to compile anything (like
your Band example) on the system is hard, as no symbol files are
included, and also no source code to recreate them. Also, there are some
.Mod files included, but not the ones changed by you? Perhaps I am
missing something obvious...

Last but not least, you provide the Bitstream file for programming an
FPGA. As far as I know, the format is specific for each FPGA model, but
you do not write which FPGA model you used/tested it with. And the
"supported hardware" does not make it any clearer, as if I am not
mistaken the original board used a Spartan-3 and the Pipistrello uses a
Spartan-6 (I did not check the others but probably they use different
FPGAs as well).

Don't be scared by my e-mail, see it as a way you can improve your
project page :)
