Yay! Wait, what?
I group them manually, if that's what you're asking.

I just said that, didn't I? I don't program it. I don't have a program to use groups in Axe. I, manually, via buttons, navigate the OS and manually group my levels. Manually. Not programmatically.

Groups are readable in axe, it's 2nd+9 (like 2nd+8 is appv, 2nd+9 is grp)
The Axe docs don't say how groups are formatted, but iirc it tells you to look in the "TI-Developer's Guide" for help on that.

I've checked WikiTI, the TI-Developer's Guide, and a file format guide, and I was unable to find anything about groups.
However, there is a bcall to deal with ungrouping, but I haven't found anything on creating groups except bcall 50C5: GroupAllVars, which groups everything in RAM. I might be able to play around with group files tonight, see if I can figure something out, since I want to know for my tutorial as well. It must be a bunch of programs in one file, though I'm not sure if there's some sort of header data, and where the program name fits into the file.

Alright, Now that there are level editors, here's a challenge for y'all:
Let's see who can come up with the best levels.
Go!

Hey, this is fantastic. I tried to make a couple levels, but there's two things: I don't like how I have to go into three different programs to edit levels, you might want to make a menu screen interface type deal, really simple, saying like, do you want to edit the shimmery stuff, the mines, or the land and other stuff? It would be really easy. Also, in the mines editor, I either placed all the mines in the top left corner, or only placed like two or three but couldn't delete them properly. You might want to make it so you can't have two mines in the exact same space.

I have splendiferous news!
The bug with Miner and the mines in the topleft corner has been solved! I rewrote the program, and, while I was at it, added a new feature: whenever you use +/- to change the mine you are editing, if that mine has not been entered, it'll save the position of that mine, so when you come back to it (using +/-), you'll be in the same position.
Miner 2.0 is not quite done yet; I've got some display options I wanna implement and I want to have the rectangles of shimmer show up as well., but it's just about done. I'll get it finished up and then get Shimmer working, and then I'll upload them both.

looks great !
Good joob

Hey, thanks! But uh, how'd you see it? Are you stalking me?!?!?

Of course I am.
You don't know anything about me
