Baseball game crash: HALT?

[tacrec]

Don't remember ever seeing HALT before.  Is this screen a clue as to why it crashes sometimes?

Is that All-star MLB.  That cartridge is known to crash, dumping Intellivision register data on the TV.  Didn't know the emulator crashes as well.  The 1BE8 could be the location of the last instruction; it is in the exec rom.

There is a Halt instruction on the CPU.  It has a binary value of zero.  jzIntv writes "HALT!" to stdout when that happens.  This is the kind of thing that happens when the CPU reads code as data.

 

As is pointed out already, the Program Counter is in the 1xxx range, meaning the Executive ROM read a Halt instruction.  That address is probably from the Exec function to write a number on the screen.  Perhaps a hacked ROM caused the issue.
