So with it all nice and done, I went to test my MidSpace version 18 on a real Atari 2600 with my Harmony cart. To my horror, I discovered the screen jumped whenever I lost a life. This was I think at 9 this morning. I then spent the next at least hour and a half trying to fix it. Part of that went to changing the title screen tune since I wasn't really liking what I had in there then. I think my new song sounds more ominous. So after 90 minutes of working on the thing, I made the scanline count steady at 262. But one thing is bothering me with the Stella emulator. It says the scanline count is steady but when you go to test it on a Harmony cart, the screen jumps a little anyway. Why does that happen?
Nevertheless, I think I have it under control and working well.
