My .s is identical. Strangely using nspire-as on the .s file reproduces the error on my side.
I see:

.LC2:
   .word   .LC0
   .word   .LC1

Which is not good, GCC doesn't make it relocatable by Ndless.

I'm afraid you will have to use something like this:

int main(void) {
    type1_t test1 = {"foobar"};
    type2_t test2 = {"foo", "bar"};
    nl_relocdata((unsigned*)&test2.s1, 1);
    nl_relocdata((unsigned*)&test2.s2, 1);
    printf("test1.s: %s\n", test1.s); /* Prints "foobar" */
    printf("test2.s1: %s\n", test2.s1); /* Should print "foo"; doesn't */
    printf("test2.s2: %s\n", test2.s2); /* Should print "bar"; doesn't */
    return 0;
}

How much is this a problem in your case?
If it is too annoying I will then  have to integrate tangrs's ELF loader with its drawbacks.

Hey ExtendeD, what about being able to open the Scratchpad while in a game/program? I'd love that

Integrating Ndless with the OS tasks management would be rather difficult.
But being able to suspend the current program execution and restore it would be possible. Maybe I could expose an API for this?

Also, would it be possible to speed up the game like in some computer emulators?

Programs must implement CPU speed tuning themselves for this, or you can use Nover.

Well what's wrong with it? Did you send Ndless.cfg.tns along with ndless_resources.tns? What kind of file are you trying to open?

Supporting the "cx,touch,click" syntax isn't much work for me anyway.

Excale suggests that the config file value contains {CX_program,[touchpad_program,[clickpad_program]]}.

The file name is passed in argv[1]. I just haven't had the time to update the documentation (anyway this update is useless as long nespire/gbc4nspire/mViewer/nPlayer aren't updated too).

I remember some of these names I got my TI-86 in 1996 or 1997.
