I tried looking everywhere at Test Unit:Yidao as someone said in 2 other threads but still can't find it. Do you need to purchase the DLC for it to appear?

I would like to know how to unlock that last fight in the training room. Also I'm missing two custom colors (one of them appeared after buying the DLC, but is still locked). Is there a guide of what's needed to do to unlock the custom colors? I like the references, I don't understand why the "Rockman X" reference has silver hair and "Copy-X" has blonde hair. And the last three colors I am not sure, are "Rockman Dash" references (the monkey, the pirate lady and the old guy)?...

It's the only one I'm missing and I'm curious. It's the color between Wind and Blue Hero.

I was watching a friend stream this in discord and while some bosses are a joke, some are brutally hard and/or unfair. Think the one that gave him the most problems was that lightning dude (forgot his name) who shot a bunch of lasers at you.

I like this game so far, but unfortunately I've experienced a lot of slowdown on both the wind and fire stages. Increasing/decreasing the screen resolution didn't seem to help. Is this just a problem on my end, or are other people having this problem too? And if so, how do I fix it?...
