Error when trying to install Intellivision.

[LorenzoA]

Newbie here,
I'm using a Pi Zero and want to install Intellivision onto a Retropie I'm using to build into a NES cartridge.

On a USB thumbdrive attached to a hub connected to the Pi Zero I have: 4 unzipped roms with a .bin extension in the retropie\roms\intellivision folder and the Executive ROM: exec.bin and Graphics ROM: grom.bin in the RetroPie/BIOS folder . I don't know if the Pi copied all of that over when it copied the other systems' roms, but I'm assuming these files are on the Pi now.

The problem is this: I install the jzintv emulator in retropie's setup menu, but received these errors: could not successfully build intellivision emulator (/home/pi/Retro-PieSetup/tmp/build/jzintv/jzintv/bin/jzintv not found).

The icon on EmulationStation hasn't appeared and I don't know what do I do. Any suggestions? If I'm going to need a command line to get the emulator installed and working, that will be new to me.

Additional hardware info:
Powered with a standard cell phone micro USB charger powering the Pi. It's a Pi v4.1 using SD image from the website. I have a keyboard connected, bluetooth dongle, USB thumbdrive (with the Retropie folders for BIOS, configs, roms created by the Pi after it was installed), and an 8bitdo SNES30 controller attached via the USB cord (next project for me because I've been having trouble getting it to work consistently.)
