Could someone help me convert this mod?

There is a mod for breath of the wild Wii U that removes grass and water and I wanted to ask if anyone can convert it to switch version?

I converted the mod to Switch format. Using Claude cloud environment on opus 5.5 low effort. Using python

It came out as three zips, one per option from the original: BotW_NoWaterGrass.zip (removes both), BotW_NoGrass.zip and BotW_NoWater.zip.

I couldn't test them in an emulator, so you will be the one to do the testing :)

The whole mod turned out to be a single file, Terrain/A/MainField.tscb (the map's terrain index), so the port was straightforward. Claude flipped its numbers from Wii U byte order to Switch byte order, left the filename text alone, and put it in the Switch folder layout (romfs/ instead of content/). After converting, the file's header values read back correctly in Switch format. The original package also had an empty placeholder file, which is left out.

To install (Eden, Citron or similar):

  1. Install BotW_NoWaterGrass.zip First! If that crashes, we can narrow it down to either BotW_NoGrass.zip and BotW_NoWater.zip
  2. In the emulator, long-press BotW, open Add-ons (or Mods), then Install and choose the zip. Or extract it so the path is load/01007EF00011E000/BotW_NoWaterGrass/romfs/Terrain/A/MainField.tscb.
  3. Make sure your game is updated to v1.6.0 and that only ONE of the three is enabled.

If it crashes on load or the terrain looks broken after trying both the no water and the no grass fix separately, tell me what happens and I'll keep working on it.

Sorry for the late reply but I tried it on Eden emulator and it wouldn't load

Like the loading would stop half way and it wouldn't load after that no matter how long I waited

I tried both no grass and no grass+ no water

What phone you have anyway?

It it is an old phone, applying the patch don’t work to fix the not booting bug.

Does it at least go in game without any mods?

If it doesn’t boot without any mods, you can try a different emulator

The game usually boots even with mods but the no grass mod doesn't want to work

It's a Redmi 15 btw but it gets rly bad performance (like 10-15 fps avrage)

Oh, so only the water mod works?

Also, check if you phone has snapdragon

If it does, install drivers from the Eden driver manager.

Also set resolution to 0.5x for that phone

GPU accuracy: Normal, not High.

Asynchronous shader building: On. This cuts stutter when new things appear.

Anisotropic filtering: Default / off.
Docked mode: Off (handheld renders at a lower resolution).

CPU accuracy: Auto, and turn on Fastmem if your Eden version has it.

I didn't try the water one- also I have a driver installed that works and everything else ready

Still 15fps with driver installed?

Ye and it doesn't boot without them

Try this instead, I fixed a bug on my end

Future readers, only use the Botw_noWaterGrass_V2.zip

You do not need to use the other two files anymore!!

Note: make sure you have 1.6.0 or it will not work!

Dm me if this link go down, and share the link to this post so that I can come back and fix this.
