I don't think that's possible, except when drawing graphs. TI-Connect lets you send 133x83 images to set as background on the graph/trace screen.

There was a program that let you do this on the home screen on monochrome calculators, but I'm pretty sure it would be way too slow on the color calc.

nah, the graph screen is only 265x165 large and bgpics are half that, stretched up. Normal 8xi files are 265x165 but only got 15 colors + transparency.

You can't. The only way is to use xLIBC backgrounds or sprite sheets then generate a full screen image from it (sort-of).

Animated GIFs could be possible, but I don't think they are natively supported. There are a number of limitations to take account of like screen size (width and height) color depth (I think the CSE is 16 bits) and file size.

Technically, if you limited the image to black-and-white 96 x 64, the TI-83 could play animated gifs. It is just a matter of taking the hardware limitations into account and having a viewer program for your gifs.

With xlib you could have a video file using 80x60 images with 256 colors, but each frame would take 4800 bytes and the video would play at around 5-6 FPS. You would need to convert each frame one by one. http://dcs.cemetech.net/ and the xLIB 84C topic on Omni probably have some helpful doc.

YEah that's my favorite part as well as the extra BASIC commands from xLIB and Celtic2CSE.

Indeed, although I wouldn't recommend using it in BASIC games until you are very familiar with the language and mastered it. In the case where you use multiple sub-programs, only the main program can be ran from archive directly. Using lowercase letters can be a problem when it comes to free RAM because each char takes 2 bytes instead of 1.

javascript:void(0);

EPPP!
when i DO rarely prgm,
i dont use lowercase....i only use it for text to be displayed.
scary... O.O
with the programs that have other programs that run with it...
i noticed 2 that you cant run it without unarcing them...
just one slight annoyance :banghead:
