Some of you probably remember Gary Kitchen's gamemaker on the C64. Too bad there wasn't a similar program that would make it easier to create games for the 2600,5200 and esp. 7800.
I can dream can't I?
Jeffry Johnston has done a little work in this area for the 5200. As a matter of fact, Haunted House 2 and Combat 2 Advanced were created with his software.
