42bs Posted August 21, 2023 Share Posted August 21, 2023 Three new boot intros: Tom&Jerry&Julia: Julia set walk with Tom & Jerry calculating in parallel (firsty on boot intros): Yet Another Rotating Cube (but in 512 bytes): Algorip - The algo was ripped from Algorift by Marquee Design: Sources as usual on github. .j64 do _not_ work on SKUNK, you need JagGD or BPE (runs a bit to quick). 14 Quote Link to comment Share on other sites More sharing options...

Cyprian Posted August 21, 2023 Share Posted August 21, 2023 (edited) well done @42bs and thanks for sharing the source code as I have no JagGD I encourage you to prepare a loader for Skunk Edited August 21, 2023 by Cyprian Quote Link to comment Share on other sites More sharing options...
42bs Posted August 21, 2023 Author Share Posted August 21, 2023 You mean instead of SKUNKs firmware? No idea how to replace it and more important restore it again. Quote Link to comment Share on other sites More sharing options...
42bs Posted August 21, 2023 Author Share Posted August 21, 2023 Ah, sorry, too much sun today 🙂 A loader that mimics the Jaguar BIOS. Put it on my things-I-always-wanted-to-try-out list 3 Quote Link to comment Share on other sites More sharing options...

Clint Thompson Posted August 21, 2023 Share Posted August 21, 2023 Video looks amazing, I'm guessing this is due to PAL though as I'm running NTSC on Model M: Quote Link to comment Share on other sites More sharing options...
42bs Posted August 21, 2023 Author Share Posted August 21, 2023 Hmm, this is strange. Video setup is done by the BIOS, so I wonder what happens. I checked with 60Hz, but never with NTSC. Is it via RF or SCART? Quote Link to comment Share on other sites More sharing options...

Maybe it is a result of the checker-board pattern? For speed reasons I write only every second pixel but switch X on every line.

Cyprian Posted August 22, 2023 Share Posted August 22, 2023 looks like NTSC artifacts Good example of that is Atai XL Hires game Ultima IV. Here hires with no artifacts (emu) and here with NTSC artifacts: Quote Link to comment Share on other sites More sharing options...
+Stephen Posted August 22, 2023 Share Posted August 22, 2023 Using s-video (or even better, RGB) will eliminate the artifacting. Composite and RF will have the problem. Quote Link to comment Share on other sites More sharing options...
Clint Thompson Posted August 22, 2023 Share Posted August 22, 2023 Composite is the only option for me currently. It’s not a big deal ultimately, just some bizarro I noticed since I love trying these things. 11 hours ago, 42bs said: Do you see these stripes also with the other intros?
