Oh, if you want to uncensor the the game at least partially, you just need to edit one line with AssetBundleExtractor.
As of version [v20210522a Supporter] the material to edit is still "Unlit Mosaic" path ID 8.
Looks like this changed, unfortunately. The new Unlit Mosiac reads as such:
0 Material Base
1 string m_Name = "Unlit Mosaic"
0 PPtr<Shader> m_Shader
0 int m_FileID = 0
0 SInt64 m_PathID = 231
1 string m_ShaderKeywords = "ETC1_EXTERNAL_ALPHA"
0 unsigned int m_LightmapFlags = 4
1 bool m_EnableInstancingVariants = false
0 int m_CustomRenderQueue = -1
0 map stringTagMap
0 Array Array (0 items)
0 int size = 0
0 vector disabledShaderPasses

0 UnityTexEnv second

0 float y = 1

0 float x = 0
0 float y = 0

0 ColorRGBA second
0 float r = 0
0 float g = 0
0 float b = 0
0 float a = 0

and attempting the previous change results in what I think are inverted colors on the dick, with the mosaic remaining in place. I'm thinking that UnlitCensor on PathID 13 or Censor on 24 might be the new culprits, though I'm not well-versed in this sort of editing so the best I can do is sorta poke around and report back if I get any good results.
