It was immensely popular here in Brazil, mainly because it arrived in 1983, yes, late, but here the second generation lasted until 1988/89 (when the third generation arrived).

The market here in the 80s and 90s was much more closed; importing electronics was prohibited, except if the company opened a branch in the country or used a local company as a representative (the most common). However, on the other hand, piracy was considered legal if reverse engineering was done in the country.

The Odyssey shone brightly at the beginning, with good marketing campaigns, translated manuals, and peripherals were also released, but soon the 2600 clones became more successful, since, at that point, there were about 5 companies making 2600s (clones, without any official authorization).

The 2600 arrived at the same time, but via clones, and it took a while to receive official representation. The 2600 obviously sold much better, but initially the Odyssey sold more.

We had a few arcade-style game cartridges, and also a music cartridge that came with a piano-key overlay for the membrane keyboard. And an assembly language cartridge, which I’m pretty sure only displayed one line of assembly at a time, and the output was a single line of text about 10 characters long. There was no way to save anything, and I’ve looked up an image of the cartridge which sells this positively as “Shut off the power and it erases eveything automatically so you can start a new program any time you want!”

They must have been pretty popular in Australia because many places sold cartridges, even petrol (service/gas) stations. Pretty sure some video rental places also rented cartridges.
