I'd love to get a thread going discussing the various software that is used in arcade construction. I've seen many programs over the years come and go, many links are dead. I wanted to do only free software, but there are some very good paid progs out there so I am including those. If there is something like this already, I'm stupid and didn't find it.
Wow, I AM stupid. Just found the Wiki.
However, enough folks responded that I'm gonna update the thread anyway.
