Yeah I saw this, I wonder if it flickers a lot on calc because I don't have a 84+ calc to test it on. And he seems good at ASM indeed, or at least at making games with it. He's ThePenguin77 on UTI btw. I hope his stuff gets noticed by the community.

Before 16 lv gs, I only saw 7 and 8

Yeah, I was pretty impressed by the variety of assembly he's done.  Did he just pop up or was he in the community for a while?  He seems too experienced to have just started recently.

EDIT: And by the way, any shade of grayscale is possible.  I can make 256 color grayscale if I wanted to.  The question is, is it noticeable?  I mean, does it really look any better than 8 color?  Can you actually tell the difference between the 11th shade and the 12th shade?

Oh ok. Ya, it is actually pretty impressive. There are sixteen colors pretty distinctly noticeable but your contrast does have to be set and the darker and lighter ones are a little hard to see, but the middles ones I thought were easy. The pictures look quite good that he provides. I don't know when he popped up but as DJ said he apparently joined over the summer.

I didn't really have an interest in the 16-level GS.
You just can't make fast games with it.
If you could, then I would be into this.
Otherwise, meh.

However, that author has some AWESOME games in his profile.

I loaded it up onto my calculator and I noticed some very prominent rolling patterns, not just flicker.  From what I've seen flickerless 8 scale looks better than this kinda flickery 16 scale.  Heh he does have some very awesome games and utilities on his profile though, like that 1D game! ^^ I'm hessitent to put that ram clear startup app on my calc though because it writes to the OS and I don't want anything bad to happen, especialy durring crash resets where things might go wrong.   

He's a really awesome programmer!  I really like his Tetris Marathon, Stopwatch, and Orbit programs.  The games are really fun!

Ya, that Tetris game is awesome. It's the best grayscale one I've really seen.
