This is going to probably sound stupid because I'm very new to MAME, but oh well. So yesterday I downloaded a shmup called Viper Phase 1, and I really wanted to play it. But before I could, it had to do this thing (don't remember right now) where I had to wait 999 seconds. So I just decided to wit until later, then I shut it off.
Fast forward a few hours later, and I open it again, but instead of the counter, it now reads:
And now, no matter what I do, even deleting it and reintalling it, it still reads the same "HARDWARE ERROR" message!
Sorry that this post is so long, but I really need some help.
Thanks for reading.
