That's because that NatFeat is only implemented by Hatari, but not by Aranym.

 

The principle is the same as with other natfeats:

- get the ID of the function, by executing the NATFEAD_ID opcode, passing it "NF_DEBUGGER" as function name. If that opcode does not throw an illegal exception, and D0 after the call contains some other value as zero, the feature is supported.

 

- or in the subfunction number. In your case, the feature does not have any subfunctions.

 

- pass that value to nf_call, along with any arguments (if any)

 

tests/natfeats/natfeats.c in Hatari has some example code, as well as the various nf_*.c files in mintlib.
