There needs to be more emulators for 1st generation consoles as I have only found 1 and it's so old it only works on DOS so you need the DOSBOX emulator just to run it. The ODYEmu emulates the Magnavox Odyssey, the first ever video game console made in 1972, but it was made back in 1999 when DOS was still being used. There needs to be a new emulator for the Magnavox Odyssey that works for Windows, iOS, and maybe even Linux. I know 1st generation consoles are really old in terms of video games but that doesn't mean that there's nobody out there that wants to play them.

In case you aren't sure which consoles are in the 1st geneneration here's a list:
