If so, they won't be talked about in the technical sense, like how to display them.  This lesson will be mostly about displaying text.  I know that some people are eager to get to sprites, but if I talk about them too soon, people might get lost, and I certainly don't want that to happen  ::)

Oh, I'd say somewhere around 50-70

Wow a lot :O, but I think it's better this way than squishing everything in very few page and making it harder to understand in the process.

I couldn't have said it better myself :D  For example,  chapters 8 and 9 at first were going to be one chapter, but then I realized I was putting way too much information in for the person who wanted to practice what he learned

I think there were a couple of typos in lesson 7.  Most notably, there was a comment saying '10 times' on a loop where b was 5.

Lessons 7 and 8 were a little harder to follow, but I think this is necessary as they cover some pretty hard stuff. :)
Still, excellent guide! :D

Well, my goal is to make sure that everything, in the end, is understood.  Is there anything in lessons 7 and 8 that's still giving you trouble?

Nothing's giving me trouble with yours yet, but once I get to day19 or so of Asm in 28 I can't figure stuff out.

My favorite thing about your guide is how it shows stuff at a lower level than Asm in 28, and it's helping me a lot with certain things in Asm in 28. ;D
(atm, the hardest think for me to understand is getting key-presses from one of the ports, as is covered around day 22.  I'm pretty sure I'll understand it once you explain it on Lesson 65 or so. ;D

I felt like your jumps around a little when you introduced all the registers. =\  Maybe it's just me. ;)

Oh, I forgot to mention this:
Quote
One byte registers are ONLY A, B, C, D, E, H, and L.
What about ixh, ixl, iyh, and iyl?  Can't you use those also if need be?

(Sorry if I'm wrong about anything. :) )

That's a good calc84maniac or Iambian question, since I'm busy for the rest of the day and can't look those up.  As far as I know you can't use ixh, ixl, iyh and iyl in functions that require a 1-byte register

You can (but not on Nspire since TI fails). Otherwise we wouldn't even name them -- you don't see sph and spl.

Oh, well in that case...however there's no need, Ztrumpet, to mention ixh ixl iyh iyl immediately, especially since unofficially, you have to use h and l anyways to access these four.

By the way, can you explain further why these four registers don't work on the nspire?

The Nspire's z80 emulation isn't complete, and many undocumented instructions don't work. Instead, some "invalid" instructions are directions to the emu to do certain things. This is how USB is done in the emulated 84+SE, for example.
