Ion/MirageOS Program Execution

New around here, but here's one I'm sure no one has done (TI-83+/84+, btw).
Perhaps someone (more like a group of people) (I'm not really good with assembly) could come up with an ASM program that could run Ion, and maybe even Mirage ASM programs in BASIC navigation and programs (not in a shell!) . Perhaps one can make an app with hooks to execute programs (like the ones in Omnicalc).
This I will say: it won't be very easy. Getting Ion prgms to work will be hard enough, but MOS much harder (closed-source).
But that's not to say it can't be done. Examples of shells running Ion programs: Mirage OS, Plasma, and oh, yes, that DoorsCS (6.0), which also runs Mirage programs (good job, there).
Farfetched? Of course. But if one does undertake this project, it would open up a new gateway in the world of BASIC programming.
If anyone has anything to say (whether it be "I'll do this," or, "Looks pretty hard," or even, "What's wrong with accessing your programs in the shell? (please don't write that!)" ), just say it! Rolling Eyes

I personally don't see there being a need for this..

If you don't like how the shell works (speaking about MOS mainly) then just make your own interface

Like an added command in the catalog? If you make it a program that you have to run every time, that IS a shell. I am not sure how the shells make it so that you can only access the game from the shell. Something to do with the include file? That is the only thing that would have to be bypassed really. Then there is just a keyhook, program detection.

And welcome to Uti

While I agree it's not entirely useful, you CAN do this.

You can write an application capable of running MirageOS/Ion/whatever programs and have it install a parser hook. That way, your parser hook will be run whenever such a game/program is run from the homescreen or a BASIC program and can set up the libraries and things that it'll need.

The MirageOS source, believe it or not, will be released one day (soon) and when it is, you could probably make a very small modification to it which installs a parser hook and uses MirageOS' runprog entry point to run things.

Or if you REALLY want to, you could modify MirageOS to do this by tacking on a little code at the end and resigning it.

This is all just speculation, of course, but I don't see why not. It'd also be a good thing to tell Kerm, because I'm sure he's looking for ways that people would use DoorsCS over the other shells.

Edit: to baorder54...some Ion/MirageOS programs use the libraries that those shells provide, so the header at the start of the program contains 0C9h ("ret") as the first instruction, so that when you try to run it from the OS, it just returns...the reason being because the libraries aren't set up yet.

Thanks for the props, and interesting idea. As said, I don't really see the point of this, but it would indeed be relatively simple to add it to Doors CS 6.

Are you sure it's not already?

True... But people sacrificed 72K for MtSQ, why not for DCS, one of the greatest shells ever?

Well, chances are DCS still has some free space in the 2 pages it takes up, so hopefully Kerm will keep adding until he's filled up the 2 pages, and then stop before the 3rd page.

I've got it! People should delete MtSQ for DCS... j/k

I haven't been paying attention to the size too much as I've been using an emulator.
So it takes up two pages? That's bigger than most if not all decent shells right now. MOS
A third page would probably discourage people from downloading it...

Kerm will avoid 3 Pages at all cost, but a few more features could be added without it going over.

Hmmm... depends what kind of calculator you have. I have an 83+SE, so I don't really care about 1-2 page apps. 3 pages, maybe.

IMO, Kerm should release two versions of DCS6 if it starts to go into 3 app pages: A version for the 83+/84+ and another version for the 83+SE/84+SE. The first version will be the smallest one and won't have as many features and eyecandies as the later one, to save space. The later one, however, should be packed with a ton of eyecandies and possibly even have DocumentDE and/or MobileTunes3 built into it.

I have a SE also so he could have 4 pages and not matter to me but a for a non SE any more that 2 would be too big. and their would be no point in making Doc DE and mt3 built in because it the person isn't going to use them the it's a waist of space even on a SE

But he they are stand alone programs even if built in, he would have to have them show up in the shell because you would have to have a way to start new Docs and to open music from within mt3.
