From the blog "Sky Editor"

User-friendly interface over vague, impossible-to-guess-without-documentation step I have a new build of Sky Editor's ROM editor available that adds some fun new features. First up is the new wizard you can see above. This should make the whole process more user-friendly (I hope). At the time of posting, there is a glitch where the Finish button won't be enabled when the extraction is complete, but this can be worked around by clicking Back then Next. The second feature is the addition of PSMD substitute animations in the starter project that was hinted at 2 months ago and showcased in the Mystery Dungeon Hacking club. The demonstration shows major spoilers, so if you haven't played the game, you should not follow this link here. As always, please let me know what you think or if you encounter any issues.
