Hey!

If an emulator does not have disk drive support, it is practically
useless. But to support persons who want to use it on original VIC-20,
there might be that the only mass memory is tape drive. Also, on
original vic-20 is just 5,5 kilobytes of RAM. C programming on vic-20 is
theoretically possible, but you cannot do big programs to it. And
persons who have memory expansion, they usually have also disk drive.

Only thing you must remember, that use the stock kernal routines and use
the jump table. Then you should be compatible with emulators and real units.
