Is there a way to test if an Nspire is CX or not (as in, any differences in screen dimensions, etc)? That way, based on that test, you can make the worlds smaller or larger.

You could have them press a button at the beginning to choose and store it in a config.

The world size I refer to is the size of the discovered part. If you walk too far from the spawn point, it'll crash soon.
The right way to prevent this is to cancel if memory allocation fails, but in C++ this works only with exceptions, which don't work with bFLT yet.

Couldn't this part be written in C then ?

How exactly would you use std::vector in C?
Also, push_back has no return value, an exception (std::bad_alloc, AFAIK) is thrown on malloc failure.

Couldn't you use gotos once the world reached a certain size instead of exceptions?

While I actually like gotos for such purposes, I'm not able to change the C++ standard and it's implementation.

Question: In the menu, how are we supposed to save? When choosing save I tried the Menu, dot, 5, esc and Enter keys and whichever worked doesn't appear to save properly. When I restart the game and  try to reload the map, it does nothing so I lose all my progress. ???

Just press "menu" then either the touchpad or clickpad "click" or the 5 key. It should freeze for a short time and then close the menu.
Or just press Esc to "Save & Exit" in-game.
If it doesn't work, could you post your current crafti.map.tns if you have one?

Just a quick update:
I'm currently busy on vacation and next week school starts again so I'm busy learning and other unnecessary duties.
Redstone is fully implemented, but some blocks are still missing, so it's not very useful yet.
However, I worked a bit on my ndless fork and got exceptions to work! It's a rather nice feature, to minimize possible crashes.
Also, it'll be using a new executable format which will load faster and maybe also make the game faster!
It'll take a while to implement it in both ndless 3.6 and 3.1 though, I don't want that it runs on 3.6 only.

Nice !
is Extended aware of this ? (So that he can integrate it in the official repo)
Well, I suppose you should finish it first :P
Good that it runs on 3.6 already, I guess it's more of a priority than 3.1, these days.
