Hello, I have created an unofficial update to this rombase.
Let me start by saying that I can't reach Li Yun (the original creator of the base) so I release this without his knowledge.
What I have done is fix some of the bugs the base has. Namely :
1. Petalburg Gym (where you couldn't get out of it)
2. The base had an issue where you couldn't import new battle backgrounds if you wanted to so that's fixed too.
3. Not a bug but I restored the original Gen 1-2-3 cries.
4. Wonderguard was broken, now it's fixed
5. Some items given to the player were "New Item" replaced those with the correct ones.
6. Egg Moves
7. TM Compatibility Table
8. Move Tutor table
9. Type Names
10. Created a table for trainers with evs (data.trainers.evs) (for info regarding this look at the EVs Trainers file in the original download in pokecommunity)
11. In Game Trades Table
12. For those who don't know eevee's evolutions can't be edited from the pokemon data in this rombase, because eevee has expanded evolution methods to 8. So I made a table for Eevee's evolutions too. You can find it as data.pokemon.eevee.evolutions .
13. Because the poke balls have been edited and Premier Ball doesn't exist in the base anymore, I made it so you get an extra Poke Ball for every 10 you buy.
14. I changed the sprites for the elemental balls added in the base and the sprite for Link Stone.(credits for these in the extra credits file)
15. In Game trades table
16. Restored Original Summary screen sprites and Type Icon Sprites cause the ones in the base weren't recognized by HMA and therefore unable to be edited.
**Now the base should be fully compatible with HMA** There could be more stuff that I don't know about but they are probably very small, if you happen to find something be sure to tell me.
