Well it just so happens that I have programmed and beta-tested both a Atari 2600 and NES Rom Maker, built from the ground up with ones and zeroes, and uses such an easy drag-n-drop interface to make complex games that are so easy to make that even a child (or Joe_Cracker) can use it. And they can both be crossplatformed to any console you can think of. I made these 2 things that happen to be an exact description of your "X Rom Maker". And guess what, asshole: I'm not selling this, or the time spent programming this, to you. Why bother with $3,000 when I could be getting paid at least 10 times that amount from people with real distribution power? I guess that sucks for you, better find a new project, Joe_Cracker!
Oh, and I'm calling these "NES Rom Maker" and "V26-78 Rom Maker" because I can. I'm planning to copyright both of these names, so please remove or change any documentation on or relating to these two names.
