the_unknown_one ... i understand that you want to use strings? Well if that is the case then xLIB wont help you much as it doesnt use strings in any circumstance. I can still give you the source ... it is extremely messy as this project was NEVER meant to be actualy used by anyone ... i just wanted to know how ASM libs worked :). That said i still need to get onto my other PC to retrieve the source.

Kevin, i will probably turn xLIB into an app and use a parser hook, because it seems to be faster. THe only problem is that i haven never made and app or a hook before :). I doubt it would be too difficult thoug. The problem i have with this is that xLIB is only ~1KB ... i dont know what i could fill the remaining ~15KB's with ... otherwise it would be a great waste of space.
A place where you can store sprites and stuff? Don't know though whether this is possible or not... IIRC Apps can't be edited when running? :(

You can fill that space with the most useless routines. MirageOS also does that I think.

Plus what about an on calc tile editor, that way tiles can be placed in programs and not waste pic space & exceed 96 tiles.

And special sprite editor, with mask built in and varible size.

plus map editor.

And how bout text compession for those RPG with lots of text, storing them again in programs.

music and music editor :P

Direct input.

Multi key test

Linking, send full varibles not just 0-255.

call labels

4 level greyscale

Filled vectors

fast biezer lines

8 way mapper

Hmmm that should fill most of the 16k. :roll:

:mrgreen:

We need a TI-83+ shell that emulate 83 games, that way we no longer need to port them


As for turning xLIB into a app, I am wondering if it could be possible to install xLIB hooks from a program instead of a very huge app? I mean if a game use both xLIB and omnicalc it will takes 32 KB of archive :shock:

You can install hooks from a ram prog ... but it is not really recommended as you cant really garauntee where the hook routine is in memory. You could store it inside a saferam location but if a romcall or something overwrites it things could get nasty.

So for now it should stay as a prgm. Maybe you could try to take down its size to 600 or 800 bytes and make it run faster maybe, if possible :) that way it would still be fast enough to have scrolling

Well i dont really see how i would be able to bring the size down and still keep the functionality as it is all routines ... no buffers or anything are stored inside the program.

Plus if i make it take advantage of hooks, it will use a parser hook which will of course render Omnicalc unusable.

I might be ok with that anyways... I'm still hoping i can make Ender's Game for 83 and 83+ (I assume it wouldnt be too hard for you to port xlib to 83 regular considering thats what you have?) although I could do far better graphics in cutscenes and otherwise by using Omnicalc.

Well why will one need OmniCalc when finished, xLIB will have all it's functionality right?

Omnicalc can display 50 sprite/seconds while all other asm lib running with the Asm( command can only display 10/seconds . Also Omnicalc can display sprites of any size from anywhere on a picture, which cannot be done by any other sprite routine. Plus it can do grayscale

Still if tr1p makes it into an app, he can change things to be even faster than omincalc.

yes. He should look at omnicalc source to see if MV use a faster sprite routine

OK, just like i promised here is the source. Please note that it is fairly messy and there is a LOT of room for improvment. This *was* only a stuff-around project that was never ment to evolve into anything you know :).
