A gender-swap EarthBound for my daughter · Tommy Reddad

I had some fun over the last week preparing a gender-swapped version<br>of EarthBound for the<br>SNES. I made use of the excellent tool<br>CoilSnake, which can be used<br>to patch and rebuild an EarthBound ROM with modified assets and<br>scripts.

The full set of changes includes things like:

gender swapping all Ness sprites, replacing his baseball cap with a<br>red bow. Includes changes to Ness robot sprites, cycling sprites,<br>climbing sprites, etc. There were maybe a dozen or so sprites that<br>needed adjustment.

replacing Ness&rsquo; &ldquo;Don&rsquo;t Care&rdquo; names with our list of preferred baby<br>girl names.

replacing &ldquo;Don&rsquo;t Care&rdquo; list for &ldquo;Favorite Thing&rdquo; and &ldquo;Favorite Food&rdquo;<br>with things that seem appropriate for my daughter.

replacing Ness&rsquo; pronouns, references to &ldquo;brother&rdquo;, &ldquo;guy&rdquo;, &ldquo;sir&rdquo;, &ldquo;3<br>boys and 1 girl&rdquo;, &ldquo;red cap&rdquo;, etc.

color swapping Ness&rsquo; dog King to match the color of our family<br>dog. This required a bit more work than expected, since color<br>palettes are somewhat restrictive for these kinds of sprites, and<br>palettes are shared across multiple different sprites. Thankfully,<br>one of the game&rsquo;s palettes is basically unused or duplicated from<br>another one, so it was possible to free up a palette and define my<br>own colors.

modifications to the credits font to add accented characters so I<br>could include a special message for my daughter in French.

It was a fun exercise but really surprisingly easy considering how<br>powerful the CoilSnake tool is. This would be insurmountable for me<br>without the tool.

I originally considered just getting a ready-made gender swap ROMhack,<br>maybe from https://www.romhacking.net/. There are actually a few<br>different ones floating around, with some having a trans Ness. One of<br>the gender swap hacks apparently injects a bunch of other &ldquo;red pill&rdquo;<br>content into the game&rsquo;s text, which I didn&rsquo;t want to have to deal with<br>myself. Ultimately I decided it would be best, easy, and safest, to<br>write one myself.

Now I just need to get my daughter to play the game eventually 5 to 10<br>years from now!
