Thanks for answering.
Well, not much surprise on my end. MKXP, in my tests, is really making a difference and efforts like XPA(T), though great work, becomes obsolete in a way. I was kind of divided which one to use, actually. But thanks for posting the demo. I will definitely go through it, even if it is only for experimenting and learning purpose. I didn't know MKXP had a zoom function for the tilemap or some kind of similar build in feature. Definitely going to study that one a bit more.
