In the meantime, I guess I'll keep updating with which podcast it isn't. I don't have the heart to skip around; once I start up a bombcast I'm compelled to listen to the whole thing.
The 7-17-12 podcast, in which CPS2 boards and hummingbird masks are discussed, is not the episode I am looking for.
Listen to a recent bombcast recently? Did they not talk about Neo Geo games? Feel free to let me know about that too. It'll make looking a little easier.
