Disk based C64 games, that aren't just a single PRG file, typically use a fastloader. The only device that supports game fastloaders is the 1541 Ultimate. The Chameleon will also do the trick, but it's still in development. Everything else, which includes C64tpc, sd2iec, 1541-III, and X*1541 cables, only support standard (slow!) C= IEC routines, and in some cases one or two fastloaders like JiffyDOS or Action Replay. They all fail once the game starts and tries to load the next part.
Sadly 1541U and Chameleon both cost over €100, and neither is currently available for purchase...
