Hey Greenfuzz,
Nice to meet you!
In answer to your questions:
1) When do you anticipate Keystone Kapers 2 and Bon Voyage to be available to purchase?
DK - I expect Keystone Kapers 2 to be available for purchase in November of this year. Bon Voyage before Christmas.
2) Will they be complete box/cartridge/manual releases?
DK - Yes, I plan to have the games available in complete boxes with manuals. I'll also have Activision-style patches available for high score plateaus.
3) Do you ever plan to release the ROM for the original Keystone Kapers 2, for us collectors that are interested in it from a historical perspective?
DK - Yes, after Keystone 2 is released I'll make the prototype ROM image available.
4) Were you working on any other games that weren't released, or did you have ideas for games you never had the time to begin programming for?
DK - Yes actually. At Activision I had a complete game we called the "Levee Game". Keystone Kelly appeared in a yellow rain slicker running around ladders and platforms repairing cracks that would appear in a background Hoover Dam-style image complete with warning lights and a beautiful sun setting on the distant reservoir . The screen kernels were written such that I could change the background color on every scan line so the entire screen would slowly fill up with water if the player couldn't cement the cracks in time. There was also a mechanic to "empty" the water on the player's side of the dam to keep the game going. I'm hopeful that I can locate a ROM of that game in the future.
I do have other games I plan to release early next year and will have information about these next titles later in the year.
Thanks again for your interest and questions!
Mahalo!
