#128 Probably a problem in Denise with the new Amiga-demo "Bacon of Hope"?
First of all, Denise is a really good emulator and I like it alot. Today I watched the excellent ne Amiga-500 demo “Bacon of Hope” (available on Pouet.net for example). First, I watched it with the Denise emulator, where I didn't notice anything, that wasn't displayed correctly or some other problems.
However, at the end of this demo (see the screenshot in the attachement) its written, that it would not run correctly in the Denise v2.7 and also not in vAmiga emulator, but only in WinUAE. Then I watched it in WinUAE, but I don't see any difference.
But maybe I overlooked something, so I wanted to report, that there might be a problem in Denise, regarding this new demo, or maybe the programmers of this demo made a joke, by writing this message in the outro, I don't know?
Maybe the Denise programmer will notice some kind of incompatibility here, then it can be fixed right away. In any case, it's an excellent demo with great effects. Some things look like AGA, even though it's ECS.

The only thing I noticed that deviates is the instability in the display of the text "Extra Bacon" in the lower left corner of the screen - see the attached picture.
The configuration in denise when testing was: A500 ECS 1.3KS 512+512
PS. Regardless, denise is still my favorite emulator for C64 and Amiga 500 computers. ;)
Best Regrads,

I (the thread-starter) have also tested again, with two emulator-windows side by side (current Denise version and current WinUAE) and I also see only one discrepancy in this demo and that's the one, TOM has already mentioned, with this "Extra Bacon" logo.
In Denise, this lettering is partially not visible at all (it should appear earlier) and then, when it's shown, only a part of it can be seen, while it's normally visible on a real Amiga 500 and in current WinUAE. So this must be the problem, mentioned in the outro of the demo. But just a minor one in Denise, and surely fixable.
look at the "nfo" link at the upper right on Pouet page of this demo.
There's a description of the error in Denise there. It says it affects the "Twister part". I'll take a look at it as soon as I have time.

Ah indeed, I overlooked this twister thing and also, that it was already mentioned on Pouet. But there's also this communicated bug with the "Extra Bacon" lettering, as a second problem. I am sure, it will be fixed in Denise, as always. Thanks in advance.
I've now looked at it again in direct comparison with a youtube-video of this demo, after reading this nfo-file, and I have to say, it's hard to see, that anything is wrong in this twister-part, to be honest. Well, maybe you'll notice something, Piciji, I certainly can't say for sure, what the problem should be.
new nightly fixes both bugs
- extra bacon logo
- when left coloured twister is showing a few seconds later. ... background dots are still displayed.
Indeed, I checked the latest test version of denise 1445 and the problem is really gone now.
Thank you for the quick fix of the emulator! (nowadays hardly anyone has free time)
I will put here where the test version of denise 1445 can be found:

The thread-starter here. Thanks for wiping out these bugs. Very nice. As always, the problem was fixed immediately, which is a cool thing!
