Is it "fan game" or "fangame"?

[Q-Nova]

I decided to look into an early iteration of MFGG (via the WayBack Machine) to see how they handle this word. In the main page, they say (bold added for emphasis) "Home of the biggest collection of Super Mario Bros. fan games and Super Mario Bros. game making resources." Throughout most of the site, though, they don't use "fan game" or "fangame", instead they usually write "game". The links page is an exception, where "fangames" is used in the description for The Moogle Cavern. Note that both pages linked are from June 2002.

In a copy of what appears to be the earliest iteration (possibly a prototype) of MFGG, neither "fangame" nor "fan game" is used outside of the title and links page (where "fangame" is used a couple times). Instead, "game" is used, much like in the iteration I linked at the beginning.

Speaking of that Emulation Zone-era iteration I linked, the Wayback Machine won't let me view an archive made before June 2002. They show earlier versions, but when I try accessing them, I get taken back to June 2002. Does anyone know why this happens? I remember seeing the earlier copies long ago.
