42bs Posted January 1, 2023 Share Posted January 1, 2023 (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, 2023 Share Posted January 1, 2023 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, 2023 Author Share Posted January 2, 2023 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, 2023 Author Share Posted January 2, 2023 (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, 2023 by 42bs Quote Link to comment Share on other sites More sharing options...

42bs Posted January 2, 2023 Author Share Posted January 2, 2023 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...
42bs Posted January 3, 2023 Author Share Posted January 3, 2023 Here is an test: Text screen is only one phrase, pitch set to 0, and IWIDTH set to 5. jag_ball.zip Quote Link to comment Share on other sites More sharing options...
