the following titles were never sold, they are homebrews.

http://destroy.austin.tx.us/commodore/c128/

Dominoes 128 v2
Landslide 80 v2 (election simulation)
Name Flash 128
Stock Broker v3
Blackjack 80 (unfinished, but playable)
High Rollers 80
1000 Miles 128 (Mille Bornes)

Should they be removed?

if they are kept there are other homebrews that will need to be added like Alien Invaders..
