The rom for this prototype has been floating around since the original release of the Stella emulator and has been pretty well documented. Mark Hahn stated in an interview (DP) that he made it while unemployed in 1987 to try and sell to Atari. I always thought it was odd that he would pick a really old and obscure coin op to try and make a game out of due to the licensing costs alone (which would have turned a penny pinching Atari off). I always figured he had some half finished code or something and decided to tidy it up while he wasn't doing anything, so I didn't think much about it.
Today I was listening to an interview with Mitch Balsam (ANTIC podcast) where he claimed that HE wrote the 2600 version of Electric Yo-Yo and that Mark must have simply released the rom with the Elk Attack name as a joke (I guess Elk stuff was a inside joke between them). Mitch claimed his version was only about 70% complete before he went to go work on the Graduate add-on and he never finished it. So what I'm wondering is:
1. Is Elk Attack the same game that Mitch wrote or did Mark start from scratch? The gamefield looks a lot like Pengo's, but that doesn't necessarily mean anything since they were co-workers and may have shared code.
2. If Mark used the same code as Mitch, did he finish it up or just release it as is? The game seems pretty complete to me although a bit too easy.
3. How come Mark never mentioned Mitch working on Electric Yo-Yo when he was interviewed by DP?
I'm curious if there are two different versions out there. This new information is really interesting.
