Fuchsia is a virus, which is produced with a small chance when the blue amoeba fights with the red amoeba (0.1% in my settings), which will convert other amoeba components into viruses, and after a generation, it will become a blank area.

The part where you wrote "When there are three nuclei around..." is the first occurrence of the word 'nuclei' which was not previously defined. What it means here?

It looks like there are eight cellstates, correct?
0 = black
1 = dark blue
2 = dark red
3 = light blue
4 = light red
5 = blue
6 = red
7 = fuchsia

How to decide whether new cells are blue or red? Is that deterministic? Do "surviving" cells keep their "blue/red" type?

Since there is pseudorandomness involved ("... produced with a small chance ..."), one would probably need some sort of "background noise" to implement this in Golly, which would (at least) double the number of cellstates.

I'm not sure if the rules are sufficiently clear and well-defined as written, that may depend on answers to the above questions.

• grows from empty cell when there are 3 neighbor cytoplasm cells

• created at empty cell when there is any neighbor cytoplasm and 1~2 neighbor core cells

• cosumed ( become empty cell ) when there are 4 or more neighbor core cells

• desiccated ( become empty cell ) when there is no neighbor plasm cell

• destroyed ( become empty cell ) when there are 2 or more enemy core cells or any enemy membrane cell

• grows from empty cell when there is neighbor cytoplasm cell and membrane cell but NO core cell.

• destroyed when there are 2 or more neighbor core cells.

• grows from empty cell or cytoplasm cell when there are 3 neighbor core cells.

• dies when there is no neighbor cytoplasm cell.

• grows from membrane cell when there are 6 enemy cytoplasm cells and 1 ally cytoplasm cell.

• infects cytoplasm/membrane/core cell when there is any neigbor virus cell.

• dies when there are less than 5 neighbor virus cell and no neighbor cytoplasm/membrane/core cell.

I'm Chinese so I use Microsoft Translate, but it is not well so "nuclei" is also same as "cell core" or "core of the cell". And another type of cell is "Wall", which is white and will not change by anything so it can block ameobas, and can produce circuit like wireworld.

It is very likely that I got something wrong in some of the interactions between the cellstates, but anyway, here is my zeroth (_v0_) attempt at reimplementing the idea in RuleLoader.

There are no "wall" cells here (for simplicity, and also because the page you linked does not appear to document all the exact rules when "wall" cells are involved, and instead just says "other rules are modified when there are walls around" and gives one example).

In several places, I had to guess because there were no clear unambiguous explanations.

For example, I had to guess that "4 or more neighbor core cells" actually means "4 or more friendly neighbor core cells" unless explicitly stated otherwise, is that correct?

Also, I had to guess that "3 neighbor cytoplasm cells" actually means "precisely 3 friendly neighbor cytoplasm cells", is that correct?
