The buffering is 2 pixel columns per frame. It grabs 2 lines from every tile that needs to be displayed and places one in front of the viewing screen (160 px), one behind it, then scrolls the viewing screen over 1 pixel. The pixel column placed behind the viewing screen is used to loop the 160 px viewing screen around the 320 px background screen. I think that's the most efficient way of doing it because partial images don't support hardware scrolling. I guess that's the method you used for the SMB3 demo because the speeds are similar right? A jumper demo/video should be out by tonight.

Cool, although technically you can scroll partial images by updating their start/end x every frame (as opposed to VLE) ... but there are some issues with this as well.

Are you worried about flicker with sprites?

Never heard of gpSP and gbc4nspire ?

Anyway, That looks great AssemblyBandit ! I think you shouldn't worry too much about speed.

At least on the 84+CSE you don't have any risks of permanently losing access to ASM programs. :P

You never know what TI can do. But yeah, I don't think they'll try to block anything on a z80 calc. If they tried, the community would unlock it in two days anyway, given the knowledge some have on z80s (even if the CSE is not the same as a +SE).

I seriously doubt that they would block ASM on the 84+CSE, unless they were really concerned that the calc could get banned due to people circumventing the teacher mode. Plus as you said, the community could easily unlock it, unless TI found a nasty way to lock it again (after all, they tried with Boot 1.03). I think that calc was due to the high popularity of the Z80 line, despite the arrival of the TI-Nspire 6 years ago, and TI decided to add a color screen to that model (without much hardware upgrades besides that) to make it look more attractive. Also, they might have decided to just go the color screen route without killing the 84+ line just so that the screen is easier to read. (And trust me, after using a color calc for a while, it's kinda weird to go back to the old monochrome screens, especially that my room lightning is kinda poor.

@tr1p1ea: I'm not too worried about flicker, it can't be as bad as PacMan!
@TheCoder1998: Thanks, you should definitely get the +C!
@Hayleia: Thanks! I won't be complaining no matter how fast it runs... well, maybe a little ;)
@DJ: My +C is for games only, the monochrome one is for math now! If I had to choose which one to carry around, its the +C for sure.
