Question:Why doesn't my boss battle function correctly?
Answer:Bosses are some of the most complex sprites in the game, and require quite a lot of experimentation to edit. First of all, many boss settings are world-specific. If you use a boss in any world other than the one it originally appeared in, without changing these world-specific settings, your battle will likely be glitched. To relocate bosses to different worlds, you will need to use a hex-editor to swap certain setting bytes.

Below is a tutorial on how to make these hex edits by Zeldara109 and Mattrizzle.

Question:Why isn't (insert other sprite here) working?
Answer:It depends on the specific sprite. However, in general, it can help to check the levels in the original game that use that sprite (checking existing YI hack levels can also help), and compare the header settings and surrounding object layouts.
