yes there are 2 different forms of new pokemon in this hack, genetically altered pokemon(new types, palette, moveset etc) and there are around 15 completely new types of pokemon found around the new region.
i fixed thie glitch by doing tests in translhextion. I took 2 gold clean roms. opened one in goldmap 1.6 and one in translhextion. In GM i opened one of the routes that got glitched up. I changed the first wild pokemon to bulbasaur because i knew that it had something to do with wildpokemon data and this allowed me to see where the problem actually is. I go to the still clean rom in translhextion and use the compare button. This lists the offsets of any differencees in the roms. I saw 2 results, one the byte that i change to a 01(bulbasaur) and 2 other bytes right infront of this(not always 2 bytes). I knew i had found the problem. So i opened up my hacked rom in a hexeditor and went to the offset of the unwanted changed bytes and looked at the correct bytes in the clean rom. Changed them to the same and that fixed the problem. Get it?
Also, ive only got some small text edits to be finished and i actually have done a few extra maps that will be in the beta that werent originally intented. You will be able to travel up to the 5th town but wont be able to go in. Im still trying to think of something clever to do with National Park.
