I know how to fix this guys. I dont know but when im trying to make a titantron (not using the TT Maker by Arjun), the titantron will freeze. I don't know why, maybe it's in the coding or converting of the video. Here's my solution.
1. Use TT Maker for making Titantrons. (credit to arjun)
2. When you import the titantron you've created, It will work but the minitron will cause bug error in graphics.
3. This is the time when you need to convert also your minitron,manually by following arjun's tutorial.
4. I usually don't use TT Maker for converting minitrons it will resize the minitrons into 112x64. This will cause the minitrons to move on the left side when you import it in the game. So the solution to this is create a minitron with size of 128x64 (correct me if im wrong). And voila! You had created a custom titantron and it can also fix the bug in titantron. I hope you understand what im saying.
Thank's guys.
