Well, it hardly qualifies as a new project, but Acelgoyobis and PindurTI can be found on github now, in case anyone is interested. :P

Re: asm for computer

Btw, 2 cc's, that's cool - did it texture more than 1 pixel at the same time? Sure, it used LUTs to advance four pixels at a time, and exploited the parallelisation capabilities of the good old Pentium 1 by arranging instructions in a highly pipeline efficient way. I think one iteration took 9 cloc...

Re: asm for computer

people write 3d engines for it, beacause whit screen resolution of 1024*768 (= low) and 30 FPS, you need to calucate 1024*768*30=23 592 960 rays a second, that is more then the calucator has cycles in fast mode :shock: Real-time 3D engines don’t work like that. You don’t shoot rays independently fo...

Re: [Staff][Dev] 8-level Grayscale Routines

I believe PTI only supports 82, 83, and 83+ Yes, but the SE ROMs can also detect regular 83+ hardware and run on it (as far as I can remember). At least PTI works with ROMs from 1.15 to 1.18. The grey levels are definitely nice to see. :) I also experimented with 8-level greyscale back in the old (...

I think I did it first in 2000, maybe 1999. But I haven’t really coded anything after Acelgoyobis (2004), unless emulators count. ;) My first encounter with assembly was in 1992, on the PC.

I'll play around with some other RNGs. I simply iterated over some area within page 0 to create the fire effect in the menu of Acelgoyobis (basically scrolling up a line, ANDing the screen with the TIOS code and redrawing text with an OR sprite routine in each frame), and it looks pretty good. Here...

It's not as fast as I would like - an image which needs every pixel changed takes a couple of seconds - but it's good enough to be used in games for nice transitions between static screens. Wouldn’t it be more efficient to do it like this: Loop through the images. For each byte do the following: 1....

Does it look worse if you don’t mask out the last two bits? I can imagine that a clever dither pattern could allow achieving finer shades that way.
