Expand number of overworlds

This modification expands the number of overworlds from one byte to two (up to 65535) without changing the size of the saveblocks.

I've written a tutorial on how to add new overworlds here: https://github.com/pret/pokeemerald/wiki/Adding-new-overworlds

Yay!

That's so useful, I'll try to add it to my project, btw, I don't undersand why you removed "unk2".

I've removed unk2 as it is unused and u16/s16 values are aligned to 2 bytes (0x00, 0x02, 0x04 etc) and (pointers are aligned to 4 bytes?) so if I had left unk2 in it the struct would have been 4 bytes larger due to padding being added, resulting in 256 bytes being unneccesarily added to SaveBlock1.

I am using a branch that contains the following changes:

- battle_engine_v2
- pokemon_expansion
- item_expansion

This change here:

bugs the overworld sprites, it makes every overworld look like Brendan, like this:

Everything is fine if I don't change that. Maybe it's worth to look into it?

I'm having a lot of trouble adding this. First all the sprites turn to Brendan and then there's all sorts of glitches. The code also seems out of date. Is there an updated version of this somewhere?

All the sprites will always turn into Brendan.
You need to rebuild map related files, either by using make mostlyclean or using the touch command over the files inside data/maps/NameOfAMap on Linux.

Also yes, there is an updated version, Ghoulslash's.

Lunos, thanks for your response. So I implemented Ghoulash's system and was able to successfully make this work including the dynamic palletes. The only issue I have now is that the rain and fog palletes become all messed up (different colours) and the player character goes on top of the fog and other tiles instead of behind it
