This might be related to the C64 clock not being exactly the original
PAL C64 clock. Fastloaders require pretty exact clocking, as
emulation shows: Bero's forthcoming "Micro64" was only able to use
fastloaders after the 0,985MHz of the C64 had been modeled as
float-values into the timing model. The C-One runs at pretty exactly
1MHz, which is not accurate enough to work with fastloaders.

We're working on a solution.
