42bs Posted January 1 Share Posted January 1 (edited) Updated an old BJL demo to rmac/rln https://github.com/42Bastian/JaguarDemos/tree/main/jag_ball The demo uses interleaved screens and Z buffer. Changing PWIDTH to 1(screen mode) , one can see an interesting effect: The GFX object I'd displayed twice! So far I have no idea if this is another Jaguar bug or a feature.

+Stephen Posted January 1 Share Posted January 1 Will have to check on my GD - doesn't seem to work in the latest version of BigPEmu. Quote Link to comment Share on other sites More sharing options...
42bs Posted January 2 Author Share Posted January 2 Yes, BPE shows only the top half of the screen and instead of showing it twice it displays three times the screen. I reported it already. VJ does not display anything but does not crash! 1 Quote Link to comment Share on other sites More sharing options...
42bs Posted January 2 Author Share Posted January 2 (edited) Just found out: The Jaguar also displays the object 3 times. One has to set IWIDTH to the actual number of pixels/8 Edited January 2 by 42bs Quote Link to comment Share on other sites More sharing options...

42bs Posted January 2 Author Share Posted January 2 Found out what is wrong in BPE: It seems it does decrement also the counter for writing Z buffer. So doubling the number of bytes to write (or pixels), fills the Z buffer and then it works. 1 Quote Link to comment Share on other sites More sharing options...
