@yfzdude Actually thought we had this one.
I sent back and took a CLOSE look at emulators.cfg (where you add the link to the hack file) as I found it odd that mine was already there.
What I realized is that it was there, but for the tzintvecs (which I assume has something to do with running things in the expansion port). So, I added it to the main program as you can see below, but still nothing. Changing the JS1's to JS0's also made no difference after this fix.
jzintv = "/opt/retropie/emulators/jzintv/bin/jzintv -p /home/pi/RetroPie/BIOS -q --kbdhackfile=/home/pi/RetroPie/roms/intellivision/hackfile.cfg %ROM%"
Advanced Controller Mapping %ROM%"
default = "jzintv"
jzintvecs="/opt/retropie/emulators/jzintv/bin/jzintv -v1 -s1 --kbdhackfile=/opt/retropie/configs/intellivision/hackfile.cfg -z1920x1080, -f1 -q -p /home/pi/RetroPie/BIOS %ROM%"
