I followed ETA Primes videos on importing MAME and Atari 2600 files. Everything worked and the data downloaded accordingly. However all I have is "Al 5139l", "good 3819", "imperfect 1212", and "preliminary" I do not have any platforms listed as described in the video. Running latest builds of everything. What did I miss???
:::EDIT::: figured it out. Saw a few screen captures and did not realize I needed to change the first drop down to "Platform List" I am officially a n00b lol
