After a lot of messing around and trouble I finally have mons and moves from newer generations! Up to gen 6 which means I can add all mons from ORAS, including megas (which will be much later). Which is what I'm deciding to do, this does increase the amount of mons to somewhere in the mid 400s, which will take a long time but I do want to do it. I'm focusing on mons found in the original emerald for now before I move on to newer mons. 
Also if you are wondering why this screenshot is darker, there is a day night cycle now (still deciding on if I should keep that)
ALSO IF YOU HAVE DO NOT GET THE SECRET POKEMON IN 0.4.1, they will turn into krabby and aipom (because the only method of adding pokemon previously was to replace unobtainable ones) they will be fully fixed in 0.5.1 which should release very soon as its a (technically huge) but small update in terms of new mons

- 83 New custom Pokemon Sprites

- 30 New Trainer Sprites

To play you will need a Game Boy Advance emulator.

Steps for PC:

-Extract the file

-Go to https://www.marcrobledo.com/RomPatcher.js/

-Put your Pokemon Emerald ROM in the ROM file section

-Put the .ups patch in the patch file section

Enjoy! Previous save files will work if you rename the save to the ROM file, however as this demo is unfinished it is recommended to start fresh, you may even like new pokemon you didn't previously <3
