that's the Joyride Twirl WIP.xex

here you go.... I guess Sandor does not complain I just zipped the complete folder including all turbo basic and atmas 2 sources plus my MADS version. my converted version is interactive you can press OPTION and SELECT to rotate and warp. whirl.zip

Well... not sure if music rocks... I love the loading music and joyride Digi intro... but Sandors SID player is not my cup of tea...

I could peek in pascal source

But how much is precalced of the anim? 1/8 of a torus and then built by tables?

Torus.... best fx still not get 100 how its based on a twirl...

Sandor you did it? Aah I thought Tamas.... good.

I have a prototype of my voxel engine in 256 col...

Welcome back Master! Remember... the waves are (still) pounding on the shore....

Its classic mose9/11 flip per frame. I recorded it with frame blending.

I just found that in the files Tamas send me years ago. I first thought its the Joyride demo Twirl but then I have seen its a unreleased fx. It was written in Atmas2 assembler format and the gfx and tables were generated in Turbo Basic. So that was the old native coding approach before Tamas went to university and used PC cross assembler and tools... I will post these days the exe file.

aaah 293... now that explains that it sometimes fuck up and as you mentioned likely fire an DLI.... ok. thx but stupid... same like not having a rasterline counter in hardware

I am little confused in terms of building screen for the 7800 with DLL. On A8 I can have any height while on 2600 i need to sync properly to the beam. So question for the 7800 in Maria mode... do I need to build exactly 238 scanlines in PAL even I might use less scanlines for my purpose? all examples I have seen seem to pad with DLL entries to blank lines til they reach 238? I am wrong or how does Maria know when the DLL is done? assume e.g. 1 screen with a text say "PLAYER 1 START" in middle of screen... do I waste empty DLLs below that text line? when reading through the 7800basic manual it also has different heights as options...

How is the speccy pulling that off without double buffer etc???

Yeah sad that we never got software Turbo Tapes. But 4 min vs 14min is quite good only by software? Reliable?

Btw i have the next glitch... Have you ever had the issue when moving sprites in x by altering the dl that the sprite Gfx go mad at certain position??? Eg 5d xpos all 6 balls ok. Writing 5e all go corrupt???

Wow.... yesterday I watched Carol Shawns icon award on YouTube and I watched old 80s Canadian computer tv show with you explaining stuff (it was the show about games) and in background you were demonstrating eastern front on an Atari 800. Then I found in the attic my 2600 and found as well German edition of De Re Atari...

aaaaaaaaaaaaaaaaaaaarg......... of course true.... missing all those convinient debug options of Altirra

@Mord there should at least something happening on screen (sprites are 4 zones a 16 scanlines). update tried per CPU loop, per VBL etc... nothing happening. the music, color etc is changing just to see if something is crashed. even writing to gfx data adress in the DL nothing changes??? wtf... but maria seems to read the DLL and DLs otherwise I would not see those balls.

I tried 5 byte header just for sake and same. Nothing changes on screen. I never had such behavior on the 7800. And again my question, do I need to construct the Screen that it hits a magic scanline number?

Is the emulator capable to show custom chip status (registers) for TIA/Maria?

a video showing that i alter via INC the sprite pos (4 byte header) and nothing moves??? what could be the reason?

Right now I am coding for standard 128k... Some of you are aware of my a8 stuff and latest stuff was released on a 8mbit cart and where I discovered the beauty of bank switching without loading from media. Now on my 7800 stuff in dev at the moment... The crippled 4K ram (actually 2k+fragmented 2k) sucks... no room for anything so no packing etc possible. So I can not lz4 graphics etc and depacking to screen etc. But well... thats what we love... working with limits.... Maria DLL is just needs some end list flag... like Miner did. And yes... always wondered that there is no Raster line counter in Maria???
