C64 Cross Compilers for Morphos?

[Britelite]

I'd like to do some machine language programming for the C64, under MorphOS.

I used to use the 68k-version of a compiler called A6, which is available on Aminet. It's probably not the best alternative, but it gets the job done

How about running Vice?

Doesn't really solve the cross-compilation problem. Using a cross-compiler instead of an assembler on an (emulated) c64 is quite a bit handier, as you don't run into problems with the assembler hogging up precious memory on the c64 and you can use a decent editor.
