Hi, I just want to know if there is any legal (copyright or intellectual property) issues for you releasing this fan project. Did you have any problems using the characters? Did you use the original characters or replicate them yourself? Did you ask for permission first to use them?
I'm asking because I'm doing something similar with another old game, and I haven't done any search yet about this legal issues that may come if I publish it, even for free.
Thanks in advance.
