So I had some time today, so I made a couple routines for the CE. It's really basic, but it works okay. I made 1bpp, 4bpp, 4bpp enlaged x2, and 8bpp, and 16bpp routines... Also, a custom text routine that can print characters 0-255.... And I threw together a simple tile mapper... And some screen shifting, along with a getpixel and color pixel. Next to do is some actual clipping.
(Technically the 8bbp and 16bbp aren't what they are... But hey, that's what I would use them for. )

Also, I provided the code and the actual file structure, in case you want to do stuff with it. Oh, and please, if you see optimizations that I should make, tell me! If I can do something faster in ez80, or my code needs some serious restructuring, that would be great to know. Thanks!

Oh, and for the curious:

Nice going Mateo! They all look really good. I'm surprised we already have a CE .inc file.

123outerme, some very smart and dedicated people have been working for some time to put one together. Mateo, very impressive work, considering that modifying the LCD mode, using interrupts, and performing direct key input are impossible (I sound as complainy as DrDnar's WikiTI edits now ). I think it's safe to say that if we ever get an App signing key for Cemetech or the community that I'll want some fast, small, drop-in replacement sprite routines for Doors CE.

Sounds good! Anywho, I've added in sprite clipping for 4bpp, 8bpp, and 16bpp. The other ones I don't care about enough to attempt just yet... But I'll do it at some point. I'm just wonder what in the world I am going to do about direct input... Hmm, time for some exploration!

I'll update it once I actually can make sure it is a-working the way it should be.

Haha, I guess this little thing is kind of unnecessary now. I did make it pretty quick; so hopefully I can scrap some of it for something, I guess. Oh well. Is anyone still interested in looking at this; even though it is still completely useless?

Useless why? Certainly a Doors CSE-like shell is going to need some well-written graphics routines, and because I'm lazy, I'd love to take advantage of your hard work.

On behalf of @kasherpete, who for some reason didn't post the question, do you still have the source for the 4bpp versions of the routines available?

The 4bpp was actually a lookup table using 16bpp - this was all done before we figured out we had memory mapped ports, so it's no longer really useful or relevant!
