Hey Snow, the name is Chaos. I'm having the same problem as the guy who made this topic, and I was wondering if you could help me out. At first I took a look at your trouble shooting and saw you found a solution. The thing is is that it's not working for me for some reason. After making my Dragonite with the OT name as Red, I checked it out and the OT keeps getting invalid no matter how many times I try to fix it. I tried out your updated trash byte.exe to see if it can finally fix my problem, dragged my Dragonite to the .exe, pressed enter as soon as it told me to and checked it again. The results were still the same. Can you help me out here, cause I tried asking this question to various people and search all over YouTube and so right now I just want to be done with it lol. Here is the file check itself to get more look on how I did it. *PS I did not put any trash bytes on the OT when I saved it, when I load it again on Pokegen it always come up as Red\FFFFryu*
