Increase move limit from 4 to 6 (Pokemon Essentials)

[SquishySquad]

I'm looking for either examples or pointers on how to increase the default move limit from 4 moves to 6. I've already figured out the max_moves variable, but changing the UI in battle to actually allow the use of those extra moves is where I am currently stumped. If anyone knows of a fangame in Pokemon Essentials that already does this I'd be most grateful.

I'd also like to change the resolution to something that scales nicely to a 1920x1080p monitor. As well as tips for increasing the general resolution of assets. Think HD textures. Again any existing fangames that already do this would be most appreciated.
