Hey,
you shouldn't execute code below address 0x200000 (and above 0x3FFFFF) as it's the start of ROM address.
That means that your code have either some kind of call or jump or stack overflow that set PC register to a wrong value.
Neopop have a debugger version that can help you to figure out where you come from (you can have the last 10 instructions, or set breatpoint at your crash address and get the last instructions too). Alas, it's great when all your code is assembly, harder when it's C.
This might help to figure out what function send you into oblivion.

What emulator and what OS are you using? Did you try to open the rom direclty in the emulator?

In this case, the know for me it's try the rom directly on the emulator, then if this works, go to the next step. One recomendation is use another emulator, like ares or Bizhawk

You can try vdmgr which includes a debugger: http://vdmgr.g2.xrea.com/download.html
you'll need the ngpc bios (to put in the bios folder)
If you have a simple project (sources + makefile) to reproduce the problem, maybe you can upload it here

Ok I saw the problem.
1. You are allowing at your code to exit outside the main function. If you don't put something to stop it (like a while loop for example), it will enter main and exit automatically.
Code:
void main ()
{
while(1){
PrintString(""Happy New Year!");
}
return 0;
}2. You are printing text without load the main or your own fonts. See SysSetSystemFont function in library.c
I think you should look at the existing examples to prevent errors of this type. If you have many doubts about "how prepare your first project" like "hello world" or something more simple, see this link, maybe help you.

well, I need help creating a simple hello world program because I want to get started making games for the ngpc.
