I hope I can do it just like everyone else and go to victory road because It's been about a week since then and I trained my pokemon such as my Infernape that is level 93 now. So since you didn't answer if there were going to be mega evolution for some pokemon I guess its not possible unless you remove some species correct to add more?
I will be releasing Beta 6F tomorrow, which has a couple of fixes. The guard will instead check that you have battled each of the eight gym leaders, checking their trainer flags instead of badges. If you have defeated all eight gym leaders, he will give no issues. But if you have not, he will stop you. This is the most foolproof way I can think of to make this work.
If you want to get through tonight, I recommend walk-through-walls. Just use it sparingly :D
I can't see why it's giving problems. The guard checks for the seven badges, and then checks that they are gold. The only way that can fail is if they are either not gold, which you said they were, or the symbols are not there, which they are. They can't be both, so it's quite perplexing.
