Thanks, I have already fixed everything and put it on mediafire :) Generally, such errors appear by accident. If I add something to the hack, it is likely that something will break. Yes Glaceon is in the game, you need to find Ice Stone in Ice Patch. The evolution stone is on the blue rock on the map with sliding stones. The evolution stone is also on Seafoam Island. :)
My hack post will be updated, but I don't know when ... Important to eliminate bugs.
PS: Generally movesets are adapted for the 4th generation. Some attacks do not work as they should, because no one has created them yet. And I have to worry you. At the beginning there were supposed to be Pokemon from the 5th and 6th generation, but due to the fact that a lot of attacks and ability do not exist under gba, I decided that there will only be Pokemon up to the 4th generation. Pokemon from the 3rd and 4th generation can only be obtained by exchanging at Goldenrod and it will always be the first form of evolution. The legends of these generations can only be found in a virtual battle in Saffron, but you can't catch them.
