I am not completely played this game, but some bugs are appearing in game such as:
1. In "bicycle contest", sometimes only black screen appears.
2. In dive, black water appearing, not blue.
3. As compare to official FireRed story, player got gym badges without gym match except "pewter city, ceruleen city and celadon city gym match.
4. In Pokemon center, when connect to Professor Oak's PC for pokedex rating, then this this is not working.
5. When caught new pokemon such as Sarapi, Kangaskid, then only showing information about "Ratata". I don't know why Kangaskid evolves in Cubone, not Kangaskhan or Kangaskhoo.
6. Pokemon use HM moves without learn, if Pokemon learns HM moves like Poliwarth learned "surf" and try this, then other pokemon showing acts, not that pokemon that actually learn this think.
7. Without map, this game is bit complicated. And sometimes starting chapter not appearing, only showing end of chapter blah blah blah. Bonus chapter is still incomplete such as "one tail vulpix". I think need better works in chapter wise story.
8. Some thinks are violent and not recommended for kids.
Please fix all these necessary, I know developer is working best, but first fix this bugs.
