You can use the ROMs from the commercially available “Intellivision Lives!” CD-ROM, dump the ROMs from an Intellivision console, or attempt to find the ROMs on the 'net somewhere. These are the same ROMs used by the MESS emulator, usually found as “intv.zip”.

This advice should be enough to help you find the right grom.bin.
I found the file, just took some persistent digging 
I also get a crash when trying to use this core. Bios files is OK, and this is the output of verbose, updated everything (core,info files & database) this morning.
I don’t see anything obviously wrong, although to be honest this core doesn’t yet produce much in the way of logs.
What source have you used for your Intellivision ROMs? Is it TOSEC or GoodINT, etc? It might be helpful to try ROMs from a different set if you haven’t already.
I can’t make this work properly.
The games load but there are no controls, the options don’t even show any buttons to configure and i’m getting tons of graphical glitches in some games like Frogger.
Using the latest nightly and latest core in the buildbot.
I tried both and both failed
Android build any time soon?
We’re working on it, but there is no ETA. If you have any expertise compiling for Android, please feel free to drop in on the conversation here: https://github.com/libretro/libretro-super/issues/710
an android core would be so nice thanks
Good news! FreeIntv is now being built for android, but no one who has been compiling it can test an android core.
If someone reading this thread is able to download the core, info files, and databases, it would be great to hear how it is working (or not working!)
I tried it on my tablet (android 5.1) and it fails on both the TOSEC and Goodsets
Are you able to post logs?
If so, I have have added a little bit more logging to FreeIntv around the BIOS load and cartridge load functions. You will need to re-download the core, but it might help narrow down which part of the process is causing the crash.
Get this with each one I try. :
Intelllicart format not detected. Determining load method via database.
Here is a full log: https://pastebin.com/yBC28cLR
I’ve updated the info files and the database. Tried it with both the goodset and tosec
Thank you very much for the log.
Are there any other video drivers available on your system to try?
edit: I have added yet more logging. If you don’t have another video driver to try, could you download the updated version of the core and try again any time at least an hour after this post?
Got tired of waiting for the buildbot, so built it myself 
Here is a log that I got using the newest build:
still no luck
You’ve been very patient, thank you. Based on our work together I think that you are experiencing a “bad opcode” error.
If you can recompile from source again, your error log will now include the opcode that has caused FreeIntv to halt. If you have time to post one more log I am hoping that the new details will be enough of a trail for @recompile or someone else to pinpoint the problem.
Could you also mention whether you are able to try running with a different video driver?
Could you clarify whether it’s the RetroArch interface that runs badly, or whether it’s FreeIntv?
I’ve tried changing from the default to sdl2 and the performance on my pc is a bit slower than the default setting. Where I can run PSX games on mednafen_psx, I can’t using the sdl2 driver.
Thank you for all your cooperation. Among other things it has helped add some useful diagnostic information to the logs.
The same ROM runs fine in RetroArch via FreeIntv on my Windows 7 x64 system so there is hope that someone else will be able to identify the specific problem and help get it working for your environment.
