Translated Realistic Ultrafly(?) Notes

How does it work:

The system uses Mode 2, because I only make use of the BG2. This is because I've been doing tests using 2 BGs. By the way, this can be achieved on the BG3 without issues, the thing is that pokeemerald does not have a way to do rot/scale to the BG3 by default.

In my example video I only have 2 maps inserted, they're both at 1:1 scale and 1024x1024 pixels wide. They both have 256 colors in wrap mode too. They're position vertically (think of Littleroot Town and Route 101).

The map loading system was mainly designed to work with this type of maps. It works with maps connected horizontally too, but there's a bug caused by the screen which has many more pixels horizontally than it does vertically. You have to load bits of screenblocks and I only load one at a time.

I only load 1 single tileset.

I haven't done a system to load and destroy event objects.

I haven't implemented a way to go back to the overworld.

I implemented a system to change the positions of the event objects dynamically (stuff like zoom, movement and such), though it may be a bit hacky.

Latios can walk through all the walls, event objects, warps and tile scripts. You can't find wild Pokémon either. Tile animations like the wild grass' do not work while you're mounting on Latios either.

You can descend with the L button and ascend using the R button. During the flight, you change the zoom from x0.5 to x0.25, it increases and decreases in increments of 16. Latios flies faster the higher it is.

The event objects all use 16 colors but because the affine is activated(?), the game can't do vhflip(?) so they're always facing to the right.

ALL THE CODE WAS WRITTEN BY ME.
