Lol, well the thing about KnightOS is it's going to have libraries, so it can be tailored to what you need so it can be bigger then TI-OS's if you have a lot of them :P although I think that is not going to be part of the OS file.

Yeah being part of the OS file is what I meant. I think Sir planned to keep it to the essential developers need and provide a math suite that comes separate. That way, people like me who no longer have math classes and who only want to develop or play games will save a lot of memory. I think the OS should come with BASIC math by default, though. That always come handy :P

wow! this is really a nice project. but how will the libraries be created? and will there be some SDK for it?

Right now, it spans four pages, because it has to, including page 00, 01, 1C, and the boot page.  Technically, the boot page isn't my code, but I don't really want to remove/change it because users will not be able to revert to TIOS if they want.  00 is the brunt of the code, and 01 is the filesystem.  1C unlocks flash.  All three pages (excluding the boot page) have plenty of room to spare.
As for libraries, DJ is incorrect - the standard version will include math libraries.  There will probably be a different version if you don't want them.
How libraries work is still being planned, but they will most likely be loaded into RAM the same way as programs, and use an lcall macro that would work similar to kcall in order to call their routines.  I may encourage users to use a jump table at the beginning of their library as well.

Strange, I would have sweared that KOS would be as small as possible and made so it is mostly aimed at devs in the first place, meaning most math libs being optional by default. My bad, then. Just try to not take 512 kilobytes for math stuff :P

Technically, you can't remove/change it unless you zap the flash chip. haha

Okay, before I get too confused...
Is the boot page just sector-protected? That means you actually can brick an 83+(SE)/84+(SE), then... :(
Good luck, SirCmpwn!

Nope, you can't erase or modify the boot page through software.

Oh, right.  The game will still take up processing power, but will be notified that it lost focus, and should pause and take up less of the CPU.  It could even disable itself until the OS comes back to it.
sorry to bump this but will the 'paused' game just be doing nop instructions? or will it just re-execute the last entry on the program stack ?(which can have horrible results when in the game you are doing a calculation like add a, a because then it will keep on adding...).
or will the program be going into a sort of savestate (pushing all used regs and so)?

Notice that this is just all speculating...

Wow I always thought that part of the memory could be overwritten/erased like the OS certificate page.

Thank goodness for that :) My bad :P
matthias1992: other processes would be executing and the game would be paused. It wouldn't be wasting cycles nor repeating instructions (At least I hope so, SirCmpwn :P)

I wish I could modify the boot page x.x I don't like having to use OP1, and I don't like having to write my own flash code.  Catch 22 much?
matthias, until I think of a better solution, best practice would be to check if you have focus, continue if you do, then halt if you don't.

I hope by halt you don't mean to execute a 'halt' instruction, unless that's the only way to handle such a thing. :P

That is what I mean, unfortunately.  I guess you might be able to call RST 38h to forcibly change threads, but idk how well this would work.

That seems like it would work, actually. It's pretty much just triggering it early.
