I LOVE that they exist. I HATE trying to put my games into them.
Of course Contra Collection goes into the R2RKMF folder, but if that does, so should Castlevania Collection, really. But then, where does the Rondo/SOTN comp go, in the R2RKMF folder, or the Arcade Adventure folder (I refuse to use the MV term....when I were a lad, 2D side-on games with large, gated maps were Arcade Adventures, and that's what they'll remain

About the only folder that doesn't bother me in some way is Racing, that's pretty easy.
Even the Arcade Archives folder bugs me, as I have the version of Metal Slug 3 that existed before the AA series, so the tile for it sticks out like a sore thumb.
And don't get me started on the Arcade Archives folder, where they inexplicably changed those tiles after the first two dozen or so games, so they look stupid if I put them in alphabetical order the way I'd like.
This isn't a joke by the way, these things play on my mind every goddamn time I boot up the machine. This pandemic is sending me around the twist.
It makes my head hurt.
