Subject: [stella] Weird timing bug, I think...help! From: Adam Thornton <adam@xxxxxxx> Date: Sat, 20 Apr 2002 12:11:54 -0500 |
Well, I finally got home, and Randy Crihfield's package had arrived with _Lord of the Rings: Fellowship of the Ring_ in it. And I ran to plug it in...and.... The text is unreadable. It's doing this weird sort of horizontal-wrapping thing, and some text is appearing in the overscan area, and in general it looks like I'm just taking too many cycles per scan line. And the colors are weird and fadey. I'm perfectly willing to believe that I'm taking too long per scan or that I've somehow damaged the timing, but there's something I don't understand. I could understand if I were taking too long per scan and stella were compensating; it could be assuming that it's a PAL game, or just silently accepting the fact that the scan line is too long and dealing with it. But the really strange thing is: the game works fine on my Supercharger. And I certainly don't understand why the SC would have any different timing than ROM. One thing that might prove a further clue: on xstella, the game appears as yellow-on-purple. On the SC, it appears as yellow-on-red. On the ROM cart, it appears as yellow-on-purple, modulo the color fading stuff. So maybe I'm somehow clobbering the color burst and the Supercharger is somehow compensating for it? (How would it do that?) Dunno. Anyway, the question is, has anyone ever seen this behavior before? I'm pretty bummed, because if it had done this on the Supercharger, I could have fixed it before telling Randy he was free to duplicate it for people. And I really have *no clue at all* why it would work on the SC but not on the actual ROM, and I'm hoping that someone here does know what's going on. Without an actual ROM burner I don't see any way to debug it, either, because it doesn't misbehave either under stella or when played into the Supercharger. Help!
