I've been trying to get SDCC running on my original TI-84, just starting with a simple Hello World Program. The following is my current code:

I'm using the Crt0 from https://www.cemetech.net/forum/viewtopic.php?t=8482&start=0
I've been using this build script on Windows 10 from https://www.cemetech.net/forum/viewtopic.php?t=7087&start=0
Code:
When built this way, the program does nothing when run through the TI-OS shell using Asm(prgmSDCC). Doesn't crash, just immediately exits after doing nothing. When run from Doors CS, I cas see the custom icon (empty square), but it immediately crashes when run. I can't seem to find the source now, but someone here said that setting the --data-loc to 0 crashes the calculator, suggesting that it should be 0x9872, or AppBackupScreen. However, when I pass this option the resulting 8xp file isn't recognized as an ASM file at all in both Doors CS and TI-OS. I also saw that the bin file generated by hex2bin was quite bloated and mostly full of FFs. Does anyone know what's going wrong?
Code:
#include <ti83p.h>
#define NULL 0x0000
__at NULL const int ALE;
volatile const char Description[9] = "TestProg";

0x80,0x01,0xFF,0xFF};

Pen = 0;
PutS("Greetings, World!");
NewLine();
}
