In 2009 Kent Rittenhouse produced a VIC-20 Multicart/Development Cart with 32 games (game set 1), games like Pac Man, Donkey Kong, Frogger, Dig Dug, etc.. The price was $28 US (not including shipping). This is what Kent said about it --
"I have recently dug my VIC-20 out of storage and have been reliving old memories playing through my games. I also decided to build a low cost MultiCart/Development Cart for the VIC-20. You can load the eprom with multiple games. There is also a prototyping area, and access to each of the 44 edge pins (by testpoints), for those who want to do their own experimenting."
"I have made a batch of these for myself & some friends, but I have plenty left over. I don't know if this would be interesting/useful for anyone here, but I have some further information on this page:

Kent Rittenhouse has now released game set 2 of the VIC-20 Multicart/Development Cart. The 32 games include such games as Artillery Duel, Cannonball Blitz, Lunar Leeper, Mountain King, Pharaoh's Curse, Satellites and Meteorites, and more.
The cart price and the website are still the same. For more information and to see the complete list of games, see the link above.
Game set 1 is still available, too.
