Using large maps from Final Fantasy VI efficiently

I'm trying to remake parts of Final Fantasy VI in Construct 2 just for my own personal use. I notice that when I put the World Map or any other maps up as a sprite it takes up a ton of memory. So, I'm assuming it would be a good idea to use tilemaps to display the overworld or Narsh and etc. I was wondering if its okay to just load the map as a tilemap and then copy and paste the entire tilemap onto the layout. I was worried because if I do that, then aren't I reusing a ton of the same tiles over and over? For example, in the overworld there are a ton of mountains. But the vast majority of the mountains are the same tile repeated and since I just copied the entire map tile for tile, i'm not efficiently using only that one tile for all the mountains. I would be using lots of different tiles that look the same in one spot each, right? So, would I have to delete all the tiles from the tile map that are exactly the same? and then remake the entire map with the tiles that are left over? I hope I explained myself adequately and I apologize if this is a stupid question. Thank you

Don't use a single sprite! For what you want to do a tilemap is the way to go. Because a tilemap re-uses identical tiles, it saves you a lot of memory and is also more efficient to draw on screen.

Use this tool to extract the tiles from your map image:

delete all doubles and create a tileset.

Then use this tool to create your map with the tileset you made before:

The maps you create with this tool can be loaded directly into Construct 2 (read the manual

on how to do)

I advice you to search the internet on general information about tilemaps in video game design

for you get an idea of how it works.

wow thank you so much for the information! Sounds like you know exactly what I meant, I'll try that method as soon as I can. Thanks!
