    Hi everybody!
    I'm currently working on my Fire Red rom hack and I've recently imported some new ow sprites with Overworldmanager (following instructions of the video from Aspiring PokeTrainer on YouTube). Everything seemed to be working... except HM Fly. Everytime I want to use it outside of battle I get a black screen before seeing the Kanto map and I can't do anything but restart the game... Has anyone had a similar problem?
     
    Yeah, I've experienced it once too. It happens because OWM doesn't look for free space after a certain offset by default. It's likely that OWM overwrote the FF bytes in the custom fly routine that you can implement with AdvanceMap. You can either download the latest version of OWM and set the Reserved Regions to 0x00000000-0x00800000, or you can manually overwrite the FF's of that routine into something else in a hex editor (so it doesn't get recognized as free space), use OWM afterwards to import new sprites. After you've finished importing the new sprites, you change those fly routine bytes back to FF's and you're good to go.
