Some glitches I have found on Beta 10B are:
1) In PC, PROF.OAK Pokedex rate system doesn't work.
2) When you are in Celadon City and you are going to leave from the left, in the second floor, the science guy (Simon), is giving you infinite Sharp Beak. Every time you speak to him, he is giving you one.
3) In Safari Zone we shouldn't be able to fight with our Pokemon.
4) In Safare Zone we should have in the menu an option to leave the Safari Zone instead of going to the door we came in.
5) In the event with Pidgey Bot 1, you can actually leave from Safari Zone if you go down and not up, skipping the whole event.
6) When you are one step out of the Safari Zone Building, if you go to the right, there are some problems with the movement and you can go up to the mountain.
7) When you are leaving Viridian City to go to Route 2, there is a kid in the trees.
8) In the event with Misty witch you trade a Krabby for Gyarados, Old Rod and Super Rod can't find Krabby. To find Krabby you have to go underwater in the grass.
9) In Cinnabar Island, right of the Pokemon Center are two trees (or whatever they are) and 2 grasses. I can't walk up to the two grasses.
10) In Celadon City, the 4th building that is left from the Pokemon Center, in the floor number 3, the computers doesn't have a message when you click on them, they only make a sound.
11) In the Pokemon League, when Huge ask me if I know the Ugly Duckling, if I press no, nothing happens and if I press yes he tells me the Ugly Duckling.
12) In the Pokemon League, in the room where the trainers fight, you can go inside the wall on the left and on the right.
13) In Celadon City, the side quest doesn't happen correctly (It skips the part that he asks to eat food and Steve comes) . The only way to happen correct is to go to the Pokemon Center first, heal your Pokemon and then go to his house, start the event, select yes when he asks you to go to his house, go to Pokemon Center again, heal your Pokemon and then go inside to his house.
Also you should change the dialogue because the tombstone isn't anymore in top-right (I have found it.) . Also the text isn't very well in the tombstone (You have to change the "player" with " \v\h01\v\h05 " ) .
14) In the Orange Archipelago, in the first Pokemon Center (with the time machine), there is Champion Delia and if you press to her, you fight with here and you have only one Pokemon left with very few HP and she has six Pokemons with full HP (her first Pokemon is level 78) . And also some times when you click on the time machine (when you don't have the battery) and it says you need a large battery, some times the player look at Champion Delia while saying that. (I am not sure if it is a glitch or you wanted to be like that, but I think it is a glitch.)
15) In Land of Origin, there are several Pokeballs that you can't take. (You might made them for that reason.)
16) In Kinkan Island, when you enter the building where the Team Rocket is, there some movement problems in some boxes.
18) In Kinnow Island, in the town, there is a guy that when you speak to him nothing happens but a sound only.
17) In Kinnow Island, right of the Day Care, the Ratata only watch left and right (it is down of the tree) and it is better if it walks.
18) In Navel Island, after I caught Groudon, I want to go back to the Pokemon Center to heal my Pokemon, but after I went out of the cave, it teleported me at the other exit for the event with the gym.
19) In route 13 there are problems with some people and if you speak to them the game crashes.
20) In Tangor Island the teleport doesn't work. Abra and the old lady do the same thing and say "Abbraa!"
21) In the island that you choose a partner for some kind of festival, if you don't choose Misty then the story stops and you can't continue the game.(And there are some problems in the text, for example, in one talk it say "Erika and you look nice partners"(or something like that) and in the next line it says "Misty and you are doing well in the festival" (or something like that) .
22) There are some problems in the talks in the Orange Archipelago League.
23) There are several glitches after the Orange Archipelago League (I can't write them all because they are a lot.) .
24) You made Clefable and pokemons like that too much powerfull, if someone doesn't have the atack "Moonblast" in one of his/her pokemons, he/she won't win.
25) You have made too much herp-derp guys in the end of the game.
Also, after Kanto League, I am always 10 levels lower than the trainers. I think you "jumped" too fast the levels there. And you did the same thing in the Orange Archipelago League.
I hope I helped finding these glitches so you can fix them.
I know some of the glitches I wrote might look stupid, but if you want a perfect hack you should fix the small things too.
Moreover, if you want, you can make some kind of guide for the sidequests after the Orange Archipelago League.
And, I want to say a big thanks for creating this game and good luck in you life!!!
