I didn't really read this cause I'm running off of 34 hours of no sleep, but I assume you made it like "event on map, parallel process, condition:'press some button', turns on switch1, else turn off switch1 and normal run speed on"
"switch1 turns on common event1, common event1 player movement +5speed"
I'll look at this later when I can comprehend stuff.
I like it though.
