FW Diagnostics - Official Ordering Thread in Intellivision / Aquarius Posted November 24 On 11/18/2021 at 8:13 PM, Kalafre said: I'm only a tad over 2 years late to the party. Is there any way to get a diagnostic for the Intellivision now? The cartridges are long since sold out, unfortunately. If you've got a multicart, you can try the ROM which is freely available here: http://fwgames.ca/roms_new/ It's always possible that someone has a spare one for sale (sadly, I do not). They don't come up on Ebay very often, if ever. You might be able to pry one from someone here though!
