I use Frodo 2.4 as well, as Frodo v4.1 doesn't seem to run as well(!?) for some reason, plus a C64 without the SID music is like a baby without his bottle! Both Frodo 2.4 and MagiC64 both run at full speeds with frameskip at 1/2, Amidog's Frodo runs at the same speed as well. But i prefer MagiC64 as that has t64 support and a better GUI.
I also agree that WinVice is the best C64 emulator out there and isn't touched. An Amiga port must be done and is very much possible.
Anyway, back to the original question, could anyone get the source code and upload it somewhere for someone willing enough to carry on developing this emu? (If anyone is interested).
