Magnavox Odyssey²
The Odyssey² is a console marketed by Magnavox in the US, originally known in Europe as the Philips Videopac G7000 in 1978. It was made by Philips and has a keyboard built into the console. In Europe and Brazil it was more successful than in the US where it was a distant 3rd place console due to weaker graphics when compared to other consoles at the time.
There were plans to have a Magnavox Odyssey³ however it was cancelled but it was released in Europe as the Videopac+ G7400. It was upgraded with a faster processor, more memory and ran at a higher resolution however the console was not successful due to the rise of the home computers.
Suggested Emulators
O2EM
O2EM is the first and the only standalone Magnavox Odyssey² emulator that also emulates the Videopac+ G7400 as well. There is an updated version of the emulator called O2EM2 that works on modern computers since the original version does not support 64 bit processors.
MAME
MAME also emulates an accessory called The Voice where it adds speech synthesis to some games.
