Possible to copy Vic-20 games to diskette and C-cassette on a c64 with the 1541 Ultimate II+?

[Mozartkügel]

I just wanted to report here that it worked for me with tape. I took the prg file of the game I'm working on and converted it into a Vic-20 tap file with wavprg, then I recorded the tap file over to c-cassette on the c64 with the ultimate 2+. After that I just loaded that tape on the Vic-20, and it gave me load error! Fortunately I just had to jerk the datasette cable a little bit and then it loaded on the second try
