Final Fantasy 6 intro bug

Post by AWJ »

In the May 14 WIP (Linux/SDL, compiled from CVS snapshot on ipher's site), there is a problem with the intro sequence in FF6. The cloud background with lightning stops and starts instead of scrolling smoothly upward.

Tested with FF6 (Japan) and FFIII (US 1.1), both verified good ROMs with no patches applied.

I can't reproduce this bug at all with SVN so I guess it was a one time bug.

I dunno about that, I've been trying every single WIP from the current back to the 08/22/05 WIP (and maybe even earlier, I got bored of downloading and recompiling old versions), and it happens to me every single time.

That sounds like a performance issue (frame skipping). Does anything similar happen with other games?

It's definitely not a "performance issue". This is an Athlon64, I have no video filters enabled and FPS is a rock-solid 60/60 or 50/50 in every ROM I have.

I haven't noticed any similar problem in any other games. It only happens in one specific place in the intro (very soon after the purplish cloud background fades in). The scrolling stops for about a second, and then abruptly "snaps" to where it would be at that point if it were scrolling properly, and starts scrolling smoothly from there.

Can anyone else with SVN verify this bug? I can't seem to reproduce it.

For some reason, I can't get the problem to reproduce when dumping a video, it only happens in the emulator window. In the emulator, even if I turn off all video filters, it still has that slight freeze during the lightning scene. But the dumped video runs the intro without the stop in the middle.

I can't check since I'm not at my own computer right now, but maybe it happens when running windowed but not fullscreen? Perhaps even only in a specific windowed mode (I found it in 512x448 DR W)

I can kinda reproduce this. Latest Linux SVN build, shortly after the intro starts, the intro seems to freeze for a moment. After about a second, the clouds skip to where they would be and the intro continues smoothly.

Nothing "kinda" about it, this is EXACTLY what happens on my machine too.

I think I have figured out what is going on. Should be fixed in SVN pretty soon.
