Enigma/Phenomena graphics corruption
Hi,
In the demo Enigma by Phenomena the text displays between demo parts are corrupted, see the attached image. This occurs with WinUAE 0.8.8R9, 0.8.21R2 and also 0.8.21R4. I've downloaded the demo from three different websites and all have this graphics corruption. Is this a bug in the emulation, or are all of the downloaded diskimages corrupt? Thanks for any help. |

Sorry, forgot to attach the image. Here it is. The text should be: "Yes!!! Let the demo begin with a weird cube"

No, havent't tried it with Winfellow (I also don't have winfellow installed). If people want to give it a try, here's a link to this cult demo:

Known UAE bug. Easy workaround: tick "immediate blitter"
I'd say over 95% of current graphics problems are caused by wrong CPU/blitter speed emulation. I am slowly adding cycle exact blitter and cpu emulation (there is no other way to fix this) to future version(s). |

I've downloaded the demo and transferred it to my A500. It seems to run OK. It's a really cool demo by the way!
So you can rule out disk image corruption. |

Yes the inmediate blitter fixes the problem! Thank you for pointing that out Tony Sune als thanks fot testing the diskimage on your A500; it is indeed a very nice demo
Additionaly ticking inmediate blit solved another problem which I was suffering lately. With SlamTilt the screen would fade to white after selecting a table and then everything would come to a halt. Ticking the inmediate blit also solves this. Tony, you said that you are slowly adding cycle exact cpu and blitter emulation, which is very good indeed. Do you have any indication if current high end PC's, say AthlonXP 1500+ and DDR memory, will be fast enough for handling cycle exact Amiga emulation? Thanks. |

I vaguely remember the demo looking like this on a real Amiga, too.

Blitter seems to run with correct speed (if Hardware reference manual's blitter cycle usage chart is correct.. I don't want to waste time by doing some experiments with my real A500) CPU timing still needs tweaking. |

Great . I believe there are still some of us with a real Amiga in the closet somewhere, so if there's testing/benchmarking to be done with the real hardware then just give a shout. I don't think we would consider that to be a waste of time
