Hey, so as said on the title, I've got two small questions concerning RMVX:
1. I'm working on a game that's sort of a visual novel (or at the least something that has visual novel-esque dialog scenes). I'm using a picture as a text box instead of system set seeing as I don't know how to change the default one. Here's what it looks like in-game:

The problem is that there's going to be times in the game in which the player must make choices, but when I input "show choices" in the event editor this is what happens:

Is there a way to make the text box transparent during choices, or at the very least a way to change the default system set for the text box?
2. Is it possible to play RMVX games without having installed RMVX/having the engine at all?
Well those are the questions. I'm hoping you guys will be able to answer them for me. Thanks!
