Oh yeah, this thing. I should see how much work it would be to try this on the CE... Since I can activate 1bpp mode, I imagine that I could get some nice results. The speed would be far greater. Could be an interesting idea...

I was just wondering the same thing 
Well, I finally went and did it.
I opted for 8bpp mode in order to have faster updates when enlarging the screen, and here are the results:
(NOTE: I could also probably enlarge the screen again and still get decent results) In 1bpp mode; it was crazy fast, but no where near the amount of pixels to look at comfortably.
Compared to the original:
Here is just the screen update code; I also copy the program to safeRAM and jump there so that way I can use proper z80 mode if needed. Kind of fun, I guess. You could even probably attempt grayscale, as it has a color index, so that might be kind of neat. Going to see how fast it goes in Mario now.
If you notice any optimizations, feel free to mention them!

My Completed Programs:
100 Digits of Pi

Color Timer

Current Main Project:
Screensaver CSE
Progress: Basically done, but I want it to check for keypresses more often. About 320 times more often. Don't know how that's going to work out.

That looks very good! I wonder how well Supersonic Ball will play?
It'd be impossible to get SSB working with mono2color because it was written with Axe, not in straight assembly.

For the CSE, yes:

Nice! That is an impressive concept; I might try to see if interlacing can be taken advantage of in some more ways... In addition, I had to relocate some sections of code for this program as it would not work on an actual calculator due to the $C000 limit. Anywho, here's the updated file if anyone wants to play around with it some more; should be working quite nicely! (Also, ionDetect also includes AppVars now, simple fix, so now you can use JamesV's converter to make all the level packs AppVars in case you don't want all the programs populating the screen.)

Also, I am not sure how these programs should be released; I believe that efforts to email the original creator are a definite must.

For the CE, not for a while. I'm a little out of commission at the moment, but I'm sure that someone can adapt it to work. The foundation is already there.
Please don't double post,there is an edit button in the topc right corner of each of your posts.
SMALL is super mario land levels, if I am not mistaken.

A download for Mario? There is one available here
