If your tile 2 appears corrupt (misc. scrambled colors), you probably used bfres_tool.exe
- DON'T use bfres_tool.exe or Wexos' Toolbox.

- DON'T scramble/overwrite your .PNGs! You'll want to keep them in a format that is easier for you to modify and compatible with the Next Cycle button!

Take heed of the red tile -- the first image (sorted alphabetically) will always be blank there! This won't be a problem for the rest of the images, however.
- You can effectively "shrink" and avoid the red tile area for most 32x32 images by upscaling them to 64x64 images!
- If your tile 2 is blank in-game, you're viewing the first image of your bfres. Nothing can be done.

If your image still has a background, you didn't delete it.
- If you're using GIMP, paste the image, anchor the image, use the color replacer tool (Shift+O), click on the background, and press delete.
- If you're using Paint.net, paste the image, use the magic wand, deplete Tolerance to 0%, turn on flood fill, disable selection clipping, click on the background, and press delete.

If your image is still scrambled, I made a "Next Cycle" button just for this occasion!
- Load your offending image into the SMM Texture Expansion Tool, click that "Next Cycle" button, and repeat steps 4-6!

If SMM isn't working now, you probably used Wexos' Toolbox or altered the base game, rather than the update data.
- DON'T use bfres_tool.exe or Wexos' Toolbox.

This is still a WIP; the first image in your Output.bfres will have a blank tile.
To fix this, I propose adding an unused frame to the top of the image list.
The only question is... how? Find out next time...

The following tutorial explains how to increase the enemy texture resolution from
16x16 to 32x32. Other image sizes have not yet been explored, but I encourage you
to experiment for yourself! You may be surprised by what you can do!

Extract 16x16 images by opening Output.bfres with bfres_tool.exe
Resize images to 32x32 images
In GIMP, Image -> Configure Grid

Break the chain icon in Spacing, changing Width to 8 and Height to 16

View -> Show Grid


The tiles appear in the following (old) order:
1234
5678


Cut and paste (as new layer) the tiles to appear in this (new) order:
1438
5276



The new 2 will automatically become old 2 for the *next* image in the entire bfres;
for example:
fly.0.dds will have a blank tile from a non-existing image, because it's the first image
(I made its old 2 blank intentionally as a work-around for this particular case.)
fly.1.dds will have the new 2 from fly.0.dds
walk.0.dds will have the new 2 from fly.1.dds
(See the claw?)
walk.1.dds will have the new 2 from walk.0.dds
So start from the end, copy the new 2, paste to the previous image's new 2 --
usually the old 6, and repeat until you've reached the beginning.

Right-click the layer toolbar -> Merge Visible Layers
File -> Overwrite name.#.dds

Inject 32x32 images by opening Output.bfres with bfres_tool_inject.exe
Click each file in the list, replace each file one by one.

Replace Output.bfres in your M#_type_name.szs, and save it.
Replace the M#_type_name.szs in your StaticSkin.pack, and save it.

Profit!
